Don't throw TypeError when object length is 0 and initialValue is undefined.
Additionally the error message should be more precise and match other engines.
Fixes#3463

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.

Math.min() and Math.max() functions should apply ToNumber on each arguments
always, even if a NaN argument occured previously and the result will be NaN.
ECMA262 v5.1 15.8.2:
"Each of the following Math object functions applies the ToNumber abstract
operator to each of its arguments (in left-to-right order if there is more
than one) and then performs a computation on the resulting Number value(s).

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.

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.

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.
