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

# swc_ecma_parser

# 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

Allow stable rust (#118) 
This pr introduces some cargo features. For `swc_common` and `swc_ecma_ast`, it introduces a feature flag `fold`.
`Fold` and `Visit` traits exist only if the feature is enabled.

For `swc_ecma_parser`, flag called `verify` is added. When disabled, we skip checking of validity of some expressions.

e.g. `{foo = bar}`

Verification is disabled by default it requires nightly compiler

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
