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.

Fully support @@species and SpeciesConstructor in Array and Promise builtins.
Also added partial support to TypedArrays, but a rework is needed in %TypedArray%.prototype functions' typedarray constructor, which is out of this patch's scope.

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.

Math.round(x) should be x it x is already integer. (ES5 15.8.2.15)
The current implementation calculates with x +/- 0.5, which isn't
representable numbers if x >= 2^52.
A correct bug fix can be to follow the spec and simply
return the number itself if it is already integer.

The register end index was not correctly calculated when
only holes presented in the arguments list of a function.

Math.trunc(x) should be -0.0 if -1 < x < 0 (ES2015 20.2.2.35). The problem
was that -0 isn't -0.0, but +0.0 in C. There were a test case for it, but
it was incorrect, because +0.0 === -0.0 in JS.

When inputs are out of bounds, we don't need to do anything in the operation.

If ecma_date_parse_year got an invalid date string, it could overread the input string.
The problem was that we compared the original str_p to str_end_p instead of str_start_p.
Additionally I simplified the parser loop.
Fixes#3388.

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

Code cleanup after #3314. Reverting already parsed '-' sign
after parse fail is unnecessary, because in this case the whole
date parse is failed.
Additionally this dead code was incorrect too, because it didn't
modify the original pointer to the string, but a local variable.

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

The algorithm is based on ECMA-262 v6, 21.2.5.6
The following helper methods are also implemented:
