Features

• Export and import name strings in them wasm are mangled
• Unused exports in wasm are removed (Tree Shaking)
  • Don't expect size improvements yet since there is not minimizer for WASM yet which does the Dead Code Elimination, which is the second part for this optimization
• Direct WASM dependencies are enforced for:
  • functions imports with i64 parameters or return values
  • memory and table imports
• generate shorter wasm runtime code

Bugfixes

• generate correct initializer for imported globals in wasm
• side-effect-free modules referenced by export * from are no longer including in the bundle
• the side-effects optimization is now possible in incremental compilation
