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.

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.
Fixes#3408

The patch also revealed a minor issue about Map[Symbol.iterator] which have been fixed as well.

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:
- RegExpExec: ECMA-262 v6, 21.2.5.2.1
- AdvanceStringIndex: ECMA-262 v6, 21.2.5.2.3

Changes:
- Parse output of Date.prototype.toString() and Date.prototype.toUTCString()
- Date.prototype.toString() is ECMA-262 v9 conform now, only TZ part changed
(Before ECMA-262 v9 it was implementation-dependent.)
- Reused day_names_p and month_names_p arrays (and made them more efficient)
- Tests updated and new tests added
Fixes#2946.

ES2015 allows primitive arguments for most of the Object built-ins.
This change implements handling for these arguments in affected methods.

ECMA_VALUE_SPREAD_ELEMENT can be used to represent that the next argument needs to be spreaded, therefore no allocation is needed.

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

This change cleans up object deallocation, and reorganizes the code so
that we are able to do object type specific operations before the
properties are freed.
Previously this would require extra conditions that would slow things
down regardless of object type. With this change however, object type
conditions are checked only once for each possible type.
