As stated in ES 16.1, "arguments" and "caller" must not be created in:
- strict functions created using the Function constructor
- generator functions created using the Generator constructor
- async functions created using the AsyncFunction constructor
- functions created using the bind

New method uses length of source to calculate raw string length.
Also bug with template literal was fixed. Template object should have
indexed properties enumerable.

Template literals already supports escaping backslash and backtick,
this commit enables escaping this in String.raw.
It also fixes invalid behaviour of String.raw when using
new line character.

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

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.

This patch will allow the user to use binary literals starting with 0b or 0B,
these literals will be evaluated in parsing time resulting an integer

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.

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

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.
