Improve swc_ecma_trnasforms (#127)
# swc_ecma_ast
 - Add PrivateName to Expr

# swc_ecma_parser
 - Fix parsing of private name

# swc_ecma_transforms

## Hygiene
 - It correctly tracks `BindingIdentifer` / `IdentifierReference`
 - Preserve `IdentiferReference` if it conflicts with a `BindingIdentifier`

## Block scoping
 - It correctly tracks `BindingIdentifer` / `IdentifierReference`


## Fixer
 - It removes useless parens.
 - It removes useless `IdentiferReference`s in comma expressions.

## Classes properties
 - public prooperty
 - private property

## Class decorators
 - implemented

Typescript & parser for decorators
swc_atoms:
 - add some atoms

swc_ecma_ast:
 - ast nodes for typescript
 - `ClassMethod` -> `Method`, `ClassMethodKind` -> `MethodKind`
 - private class method / class property
 - use separate type for tagged template literals
 - add `declare` field to `Decl`s
 - make function body optional

swc_ecma_parser:
 - rename Type to TokenContext
 - support decorators
 Note: error reporting for invalid decorator is not implemented yet
 - merge `Config` into `Syntax`
 - Use DiagnosticBuilder for error type
This is to make backtracking cheaper.

swc_ecma_transforms:
 - add `strip` pass

More works (#66)
ecma_transforms:
 - implement es2015::instanceof
 - implement es2015::typeof_symbol
 - implement inline_globals pass

ecma_parser:
 - `PResult<T>` is now `Result<T, ()>` and `Err(())` means that an error is emitted.
 - add docs

Cleanup (#64)
- rename packages to be consistent
 - `swc_macros` is removed. Now macros are imported with `extern crate macro_name` instead of `extern crate swc_macros`.
 - manage atoms with words.txt file

 - implement es2015 - classes pass

codegen: 
 - handle infinity correctly
 - disable comments for testing (it's buggy)

ast:
 - add methods about reserved words

 - organize compat

codegen:
 - use `Mark` to avoid deoptimization

swc:
 - upgrade rayon and use global thread pool instead

ECMAScript parser (#1)
- Parser and lexer for lastest ecma spec https://tc39.github.io/ecma262

  - Lexer is currently very inefficient

 - Use https://github.com/tc39/test262-parser-tests/ for testing.

 - Implement proc-macro based ast folder and assert_eq_ignore_span! based on it.

 - Some utilities for proc macro at /macros/common
