Move all codegeneration from `generateBytecode` pass to `generateJs` pass (#459)

Browse Source 
* Split 'consts' collection by content types into:

  - literals: for literal expressions, like `"a"`
  - classes: for character class expressions, like `[a]`
  - expectations: for constants describing expected values when parse failed
  - functions: for constants with function code

* Move any JavaScript code generation from 'generateBytecode' to 'generateJs'.
* Rename opcode 'MATCH_REGEXP' to 'MATCH_CLASS' (name reflects purpose, not implementation).
* Replace 'PUSH' opcode with 'PUSH_EMPTY_STRING' opcode because it is only used with empty strings
