Zoltan Herczeg 1105b43c22 Optimize Promise data structures. (#3768) 
This patch reworks several structures:

- Fulfill and reject reactions are combined into one collection. The values in this collection
are compressed: a capability followed by an optional fulfill and reject functions.
- Fulfill and reject reactions are directly stored, no need to allocate an object for them.
- The job queue directly stores its items, this saves a pointer to the value, and the
callback is replaced by an uint8 type.
- Promise status and already resolved is stored in extra_info.

Zoltan Herczeg 3d797b8836 Implement the core of let/const statement. (#3239) 
This patch implements the core part of let/const statements. Redeclarations are correctly
detected and separate contexts are correctly created for these statements. Register
optimizations are also emplyed whenever possible.

Lots of features are still missing:
 - checking the var statements in eval
 - const are treated as lets
 - single statement checks are missing
 - export declarations are exported as vars, let/const export is not supported
