Rework the core of class parsing/runtime semantic (#3598)
Changes:
 - Use the pre-scanner to provide information for the parser about the existence of the class constructor
 - The allocation of the super declarative environment is no longer needed
 - The VM frame context holds the information about the this binding status
 - Reduce the number of class related VM/CBC instructions
 - Improve ecma_op_function_{construct, call} to properly set new.target

Support parsing async modifiers for functions. (#3460)
Only parsing is implemented, so the async functions currently behave
like normal function except they return with a resolved Promise object
when the function is terminated correctly.

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

Create function variables using the data produced by the pre-scanner. (#3199)
The pre-scanner now is able to track all variable declarations and produces a compressed
stream which store this data for each function and catch block. When a function or
catch block is parsed, this information is decoded and the appropriate variables are
created. Furthermore a stack scope is created which contains the currently available
local variables and their register or literal index.

fbde788d1f Scanner rework. (#3038)
The scanner was an on-demand tool of the parser, which was triggered by certain
statements. After the rework, the scanner runs only once, and collects all information.
This information is passed to the parser.
