 - dead code elimination (Closes #607)
 - inlining

55c0258017 Remove empty expression in expression statement with top level await (#630)
Eats the semi-colon.

This doesn't compile (edit: doesn't compile the code in the tests) though because the target of that folder is ES2015. Also, this is kind of strange for me to put the tests in the "typescript" folder. Should we create something more general?

You can take over this PR if you'd like!

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
