d18e82b380 fix for 45006 (#45020)
* fix for 45006

* treat setters like getters in preceding commit; move test accordingly

* fix test baselines

* changes per code review

in `getContainerFlags`, move cases for get/set accessors
to fallthrough into the block that currently handles MethodDeclaration;
so get/set accessors and method declarations all get the same container flags,
such that during `bindContainer`, `startFlow.node` is assigned to
getters/accessors
(this changes a public api in tsserverlibrary.d.ts and typescript.d.ts
by adding `GetAccessorDeclaration` and `SetAccessorDeclaration` to the type
of `FlowStart.node`)

consolidate predicates checking whether a node is either a get or set
accessor, into `isObjectLiteralOrClassExpressionMethodOrAccessor`
(formerly `isObjectLiteralOrClassExpressionMethod`)

annotate updated test with `@target: es2020`

* fix `isObjectLiteralOrClassExpressionMethodOrAccessor`

require that Getter/Setters are parented by an ObjectLiteralExpression or ClassExpression

8d4fe5a0fb Fix unassignable properties by adding undefined with exactOptionalPropertyTypes (#45032)
* Simple first version

Doesn't cover or test any complicated variations.

* Lots of cases work

Destructuring does not. But

- skipping node_modules and lib.* does.
- call expressions does
- property access, including with private identifiers, does

* Support variable declarations, property assignments, destructuring

As long as it's not nested

* More cleanup

* skip all d.ts, not just node_modules/lib

* Offer a codefix for a lot more cases

* remove incorrect tuple check

* Use getSymbolId instead of converting to string

Co-authored-by: Andrew Branch <andrewbranch@users.noreply.github.com>

* add test + switch to tracking number symbol ids

* Address PR comments

* Exclude tuples from suggestion

* Better way to get error node

Plus add a check that errorNode is an argument to the call, not the
call's expression.

* fix semicolon lint

* fix another crash

* Simplify: add undefined to all optional propertie

whether or not somebody tried to assign undefined to them in the
erroneous assignment

* remove fix-all

635f5bdf8c Some tweaks for backtick strings
1. `getRawLiteral()`: barf if `currentSourceFile` is missing, since if
   it is, then the following `getSourceTextOfNodeFromSourceFile` will
   return a bogus `""`.

2. One `||` -> `??` change.

3. `backtickQuoteEscapedCharsRegExp`: escape the usual control
   characters except for a simple LF.  This code does get used to
   generate backtick strings when `rawText` is not given, and not
   escaping things like TAB characters can get mangled by editor
   settings.  Worse, not escaping a CRLF and putting it verbatim in sthe
   string source will interpret it as LF, so add a special case for
   escaping these as `\r\n`.
   Added test.

Related to #44313 and #40625.

541e553163 Specific diagnostic suggestions for unexpected keyword or identifier (#43005)
Error message improvement for unexpected tokens in the following situations:

* A word was parsed that seems to have a low edit distance from a known common keyword
* A word was parsed that seems to be a known common keyword and a name _without_ a space in-between
* Parsing in a particular type of node (mostly a class property declaration) got a different word or token than expected

___

* Specific diagnostic suggestions for unexpected keywords or identifier

* Don't reach into there, that's not allowed

* Improved error when there is already an initializer

* Specific module error message for invalid template literal strings

* Skip 'unexpected keyword or identifier' diagnostics for declare nodes

* Improve error for function calls in type positions

* Switch class properties to old diagnostic

* Corrected errors in class members and reused existing textToKeywordObj map

* Corrected more baselines from the merge

* Update src/compiler/parser.ts

Co-authored-by: Daniel Rosenwasser <DanielRosenwasser@users.noreply.github.com>

* Mostly addressed feedback

* Clarified function call type message

* Split up and clarified parsing vs error functions

* Swap interface name complaints back, and skip new errors on unknown (invalid) tokens

* Used tokenToString, not a raw semicolon

* Inline getExpressionText helper

* Remove remarks in src/compiler/parser.ts

0454ae4720 Loosen up the first argument type for String.raw
The [String.raw spec](https://tc39.es/ecma262/#sec-string.raw) uses just
the `raw` property of its first argument, which is a useful way of using
it in user-defined tag functions to do the work of interleaving strings
and values as well as converting the values to strings.
