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

* 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

* ensure export modifier is used before default modifier
* gracefully handle `default function`
* Revert "gracefully handle `default function`"
This reverts commit 1d8e288754.
* give better error message on default without leading export
* Issue unawaited promise error on symbol-less expressions
* Use same behavior for call expressions
* Revert "Use same behavior for call expressions"
This reverts commit 60d58132e4.
* Fix 'arguments' check in class field initializer or static initialization block
* return errorType
* Merge branch 'master' of https://github.com/exoticknight/TypeScript
* use isInPropertyInitializer
fix Diagnostics message
* Don't attach declarations to symbols in mapped types with 'as XXX' clauses
* Add test (and tweak comment)

* Add test case for 'useUnknownInCatchVariables'.
* Add new 'useUnknownInCatchVariables' flag.
* Accepted baselines.
* Add test for catch variable explicitly typed as 'any'.
* Accepted baselines.
* Move option under 'strict'.
* Accepted baselines.
* 'useUnknownInCatchVariables' is strict in command line help.
* Ensure static index signatures have an errorNode available
* Lookup static index signature declarations in the right symbol table, stop checking prototype props
* support QualifiedName when narrowing inside loops
* add test
* narrow more qualified names
* handle `undefined` of `getFlowCacheKey `
* update comments in test
* Private identifiers use standard identifer scanning
Previously they used an old copy of the identifier scanning code that
didn't handle extended unicode yet.
* gotta fix that const lint
* Cache accessibe symbol chains, type parameter name generation
* Move signature declaration helper length approximation to start of function
* Add node result caching internal to `typeToTypeNodeHelper`
* Suggestion from PR
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.
Fixes#43609.
* Allow filterType to consider union constraints of non-union types when determining never-ness
* Move impl to callback
* Baseline change in narrowing behavior into test, fix post-LKG build
* Test where relative import isnt ideal in the declaration emit
* use project relative preference for declaration emit
Fixes#39117
* Fix incorrect path matching when calculating module specifier
* Use correct baseUrl for the module specifier
This diff extends the types checked by
discriminateContextualTypeByObjectMembers and
discriminateContextualTypeByJSXAttributes to also include any optional
components in the type union.
fixes#41759 although it doesn't address the better error reporting for
their last repro, which I'm not sure how to address.
* Use faster, stricter prop type comparison when merging props in union prop creation
* Be better at determining this usage in methods, accept baselines
* Small style change
