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
