* update parser error recovery tests to use ¬ not #

The intent of the tests seemed to be to
regiment the behavior of the parser
when a weird symbol is encountered.

The `#` is now taken by private identifiers,
so `¬` seems like a good new choice for
keeping the diff small, since it also fits in
16 bits (wide emojis would be treated
as multiple characters, since the scanner
uses ++).

* Private Name Support in the Checker (#5)

- [x] treat private names as unique:
    - case 1: cannot say that a variable is of a class type unless the variable points to an instance of the class
        - see [test](https://github.com/mheiber/TypeScript/tree/checker/tests/cases/conformance/classes/members/privateNames/privateNamesUnique.ts)
    - case 2: private names in class hierarchies do not conflict
        - see [test](https://github.com/mheiber/TypeScript/tree/checker/tests/cases/conformance/classes/members/privateNames/privateNamesNoConflictWhenInheriting.ts)
- [x] `#constructor` is reserved
    - see [test](https://github.com/mheiber/TypeScript/tree/checker/tests/cases/conformance/classes/members/privateNames/privateNameConstructorReserved.ts)
    - check in `bindWorker`, where every node is visited
- [x] Accessibility modifiers can't be used with private names
    - see [test](https://github.com/mheiber/TypeScript/tree/checker/tests/cases/conformance/classes/members/privateNames/privateNamesNoAccessibilityModifiers.ts)
    - implemented in `checkAccessibilityModifiers`, using `ModifierFlags.AccessibilityModifier`
- [x] `delete #foo` not allowed
- [x] Private name accesses not allowed outside of the defining class
    - see test: https://github.com/mheiber/TypeScript/tree/checker/tests/cases/conformance/classes/members/privateNames/privateNameNotAccessibleOutsideDefiningClass.ts
    - see [test](https://github.com/mheiber/TypeScript/tree/checker/tests/cases/conformance/classes/members/privateNames/privateNamesNoDelete.ts)
    - implemented in `checkDeleteExpression`
- [x] Do [the right thing](https://gist.github.com/mheiber/b6fc7adb426c2e1cdaceb5d7786fc630) for nested classes

mv private name tests together

more checker tests for private names

update naming and cleanup for check private names

for private name support in the checker:
- make names more consistent
- remove unnecessary checks
- add utility function to public API
- other small cleanup

Move getPropertyNameForUniqueESSymbol to utility

for consistency with other calculation of
special property names (starting with __),
move the calculation of property names for
unique es symbols to `utilities.ts`.

private name tests strict+es6

Update private name tests to use 'strict'
type checking and to target es6 instead of
default. Makes the js output easier to read
and tests more surface area with other
checker features.

error message for private names in obj literals

Disallow decorating private-named properties
because the spec is still in flux.

"Private names are not allowed outside class bodies"

Add rbuckton test cases for private names

These test cases specifically exercise where
we needed to use name-mangling. They are
cases where private names have the same
description.

- private names no conflict when inheriting
- private names distinct even when
the two classes have the same name

check dup instance+static private identifiers

class A {
    #foo;
    static #foo;
}

not allowed because static and private names
share the same lexical scope
https://tc39.es/proposal-class-fields/#prod-ClassBody

refactor getPropertyForPrivateName, rel spans

refactor getPropertyForPrivateName so
it is easier to read (use findAncestor instead
of loop).

Fix bugs in getPropertyForPrivateName:
- make it work with deeply-nested classes with
and without shadowing
- make it catch shadowing when the conflict is
between static and instance
private name descriptions (these can actually
clash)

And add related spans to diagnostics
for getPropertyForPrivateName

catch conflicts between static and instance
private identifiers:
- cannot have an instance and static private identifier
  with the same spelling, as there is only one namespace
  for private names

rename 'PrivateName' to 'PrivateIdentifier'

to match the change of wording in the spec
prposal:

https://tc39.es/proposal-class-fields/#sec-syntax

The rename in the spec was to avoid confusion
between the AST Node PrivateIdentifier
and the internal spec type PrivateName.

So one uses the [[Description]] of a
PrivateIdentifier to look up the PrivateName
for a given scope.

This corresponds closely to our implementation
in the binder and checker:
- we mangle PrivateIdentifier.escapedText to
get a `key` which we use to get the symbol
for a property

f

getLiteralTypeFromProperty-check privateIdentifier

rename and simplify privateNameAndAny test case

make it clearer that all this test is showing is
that we allow accessing arbitrary private identifiers
on `any`.

Note: we could have something more sound here by
checking that there is a private-named field declaration
in a class scope above the property access.

Revert "getLiteralTypeFromProperty-check privateIdentifier"

This reverts commit bd1155c300bc3517a0543580f4790268f86e473f.

reason: the check for isIdentifier in
getLiteralTypeFromProperty is superfluous because
we do this check in getLiteralTypeFromPropertyName

Update comment in private name uniqueness test 3

I think the comments were not accurate and that we
export the error on `this.#x = child.#x` because:
- private names are lexically scoped: the code in question is not in a
lexical scope under the definition of Child's #x.
- private names are private to their containing class: never inherited

This expected behavior matches that of Chrome Canary and
my understanding of the spec

test private names use before def, circular ref

test private names use before def, circular ref

update diagnosticMessages s/delete/'delete'

per @DanielRosenwasser and @sandersn guidance,
use this style in diagnostic messages:

"operand of a 'delete' operator" (single quotes)

rather than old style:

"operand of a delete operator" (single quotes)

This is for consistency, as we use the new
style in the privateIdentifiers error messages
and it is consistent with our messages about
other operators

incorporate private names early exit feedback

and code style change to use a ternary
instead of if so we can 'const'

require private-named fields to be declared in JS

Ban private identifier in enum

As the new test, 'privateNameEnumNoEmit',

a diagnostic for private identifiers in enums.

However, when noEmit is false we
hit this assertion in the transformer.

This assertion will have to be removed
so that we have a diagnostic here instead
of an assertion error.

dts: don't emit type for private-identified field

Do not emit types for private-identified fields
when generating declaration files.

export declare class A {
    #foo;

The following would be better:

}

notice when private-identified field unused

Notice when private-identified fields are unused,
and implement the same behavior as for unused
private-modified fields.

This is used in the language server to make things
grayed out.

This case generates an error when --noUnusedLocals
flag is passed to tsc:
    - "<name> is declared but never used"

Revert "dts: don't emit type for private-identified field"

This reverts commit e50305df5fb88121486291abad14478f5339a455.

Instead of just excluding the type from private identifier
emit, only emit a single private identifier
per class.

This accomplishes nominality while
hiding implementation detail that
is irrelevant to .d.ts consumers

only emit a single private identifier in dts

In dts emit, emit at most one private identifier,
and rename it to `#private`.

* Add @private/@protected/@public test

* Fix @declaration

* draft abstraction + one usage

* Fill in necessary parsing etc

* make general getEffectiveModifierFlags

move to utilities, make the right things call it

* reorder public/private/protected

* JS declaration emit works with @public/@private/@protected

* revert unneeded/incorrect changes

* Update baselines and skip @public/etc when parsing

1. Update the API baselines with the new functions.
2. Do not check for @public/etc during parsing, because parent pointers
aren't set, so non-local tags will be missed; this wrong answer will
then be cached.

* Parser: don't call hasModifier(s) anymore.

Then move jsdoc modifier tag checks into getModifierFlagsNoCache where
they should be. The jsdoc checks are skipped when the parent is
undefined. There are 3 cases when this can happen:

1. The code is in the parser (or a few places in the binder, notably
declareSymbol of module.exports assignments).
2. The node is a source file.
3. The node is synthetic, which I assume to be from the transforms.

It is fine to call getModifierFlags in cases (2) and (3). It is not fine
for (1), so I removed these calls and replaced them with simple
iteration over the modifiers. Worth noting: Ron's uniform node construction
PR removes these calls anyway; this PR just does it early.

* Fix constructor emit

1. Emit protected for protected, which I missed earlier.
2. Emit a constructor, not a property named "constructor".
3. Split declaration emit tests out so that errors are properly reported
there.

caf0041f8a Add listFilesOnly command-line option
Msbuild currently uses a combination of `--listFiles` and `--noEmit` to
obtain a list of files to be consumed by tsc.  However, these two flags
don't suppress type checking, the results of which msbuild will never
consume.  This new switch gives msbuild a faster way to obtain the file
list.

Note: like `--noEmit`, doesn't make sense in build mode.
