After the rework it is possible to detect use before init errors for function arguments.

1) Nested function declarations should not overwrite arguments.
2) Functions should be created in the correct scope.

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

This change fixes the handling of lexical blocks when executing multiple
scripts, and also fixes a few issues with module environments.
After this change, all script files will run in the same context and
will have access to lexically scoped global variables of previous
scripts, and module environments will no longer have a bound global
'this' value.
The REPL implementation in main-unix is also fixed to correctly handle
lexically scoped variables.
Fixes#3561.

Notable changes:
* Extracted the pure JS/builtin and external C method invocations
into two new methods (`ecma_op_function_call_{simple, external}`).
* Updated parser/scanner to handle "new.target" correctly.
* Added JS test case.

Compared to utils, the functions here scan the input (e.g. uses lexer_next_token).

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.

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

Scanning should continue with `SCAN_MODE_POST_PRIMARY_EXPRESSION` in all cases.
Fixes#3360.

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 the core functionality of destructuring patterns.
Function argument/for in-of pattern are currently unsupported.

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.)
