- 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.

The modification adds support to parse /A{/ like RegExps.
That is: if the iterator is invalid it should be treated as normal
character.
This behaviour is defined in the ES2015 standard Annex B 1.4 point
This only works if the `JERRY_REGEXP_STRICT_MODE` is disabled
(set to zero).

Local variables inside the function body should be constructed after the
parameters are initialized. Furthermore arguments should be available
during parameter initialization.
