Now on the TypeScript Repo!: microsoft#30829

This is the best place to view all of Bloomberg's work on the TypeScript compiler for supporting class private fields and private methods.

This pull request shows all of our work that has been reviewed. This includes the following changes:

Parse Private Names #4: adding private names support to the parser

We have other work in progress here: https://github.com/bloomberg/TypeScript/pulls, including:

Private Name Support in the Checker #5: adding private names support to the checker
(WIP) Private name class field transformation #8: class private fields

…oft#27338)

Infer array rest as tuple if possible

Refactoring to unify updating no input files error

Default logger for projectService has assert on exceptions being logged in tsserver

Don't complain about `modules` and `outFile` options when `emitDeclarationOnly` is set.

Remove unneeded `argName` check, because it always evaluates to `true` (the `false` case is handled just before the modified line)

Update spec.md to fix minor typo

Small refactoring of getTransformationBody

* Fix GH#18217 issue for FileLog. * Refactor FileLog class to not use isEnabled property.

…r visibility (microsoft#27444)

…-exception-27338 Use safe some function to handle undefined declarations (fixes microsoft#27338)

…extends-helper adding missing semi-colon to extendsHelper

TypeScript must hoist accessors for super properties when converting async method bodies to the `__awaiter` pattern for targets before ES2016. Previously, TypeScript would reify all property accesses into element accesses, i.e. convert the property name into a string parameter and pass it to `super[...]`. That breaks optimizers like Closure Compiler or Uglify in advanced mode, when property renaming is enabled, as it mixes quoted and un-quoted property access (`super['x']` vs just `x` at the declaration site). This change creates a variable `_superProps` that contains accessors for each property accessed on super within the async method. This allows accessing the properties by name (instead of quoted string), which fixes the quoted/unquoted confusion. The change keeps the generic accessor for element access statements to match quoting behaviour. Fixes microsoft#21088.

* rename _super to _superIndex and _superProps to _super. * reinstate early exit for transformers by marking super accesses as esnext/es2017 in `binder.ts`. * adjust comment in `checker.ts` to new emit.

Moves the transformation of class properties to the ESNext transformer. Property initializers are moved to the constructor by the TypeScript transformer only if there is constructor parameter properties. This is to preserve property initialization order. It currently does not produce void 0 initializers for property declarations that have no initializer due to ESNext and TypeScript having different runtime behaviors. TS completely elides property declarations with no initializer, while I believe the ESNext would define that property on the instance with an undefined value (which is observable at runtime - propertyName in instance or for (var prop in instance) {}).
