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.

Furthermode an error is thrown when 'use strict' is used in a function with non-simple arguments
and function arguments are not moved to lexical environment when unmapped arguments are present.

A large rework because surrogate pairs must be combined.
Currently only the 0x10C80..0x10CF2 is accepted as valid identifier character from the non-basic plane.

There is no need for a specific opcode after yield because
the return and throw commands can be redirected to fake byte code sequences.

Some things are missing:
- yield* support
- generator definition in object literal
- the hidden GeneratorFunction

Registers are stored immediately after the frame pointer and an argument is dropped from vm_run.

Furthermore create unmapped arguments objects if a function has a non-simple argument.
A few destructuring pattern issues were fixed as well.

This patch implements let/const support for all "for" statements.
It includes an algorithm for cloning declarative lexical environments.

Local variables inside the function body should be constructed after the
parameters are initialized. Furthermore arguments should be available
during parameter initialization.

Remove var declaration workarounds and correctly create / use variables for modules.
Still missing: create lexical environment for automatic module conversion.
(Or remove this feature overall.)

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

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.

1) Remove an unnecessary check.
2) Check that comma is not allowed between question mark and colon
3) Create a hex decoding variant which does not throw error.
These are quality improvements, they have no negative impact.

To implement let/const, the code affected by for statements needs to be identified,
and this patch implements the basic infrastructure for that. The short term benefit
is that scanner info blocks are not generated for do-while blocks.

After changing the lexing position, the current
position of the scanner info must be moved as well.

The patch also checks whether pre-scanning is successful when scanning is,
so no need for explicit pre-scanner checks anymore.

The function names of classes were incorrectly parsed.
Also made the parsing more strict (more issues were captured by the pre-scanner).

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.

this is not too memory efficient, some corner cases requires its existence.
