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.

Timezone minutes part was always 0 instead of the proper value.

This change brings the replace operation up to date with ES6 by
implementing support for the @@replace well-known symbol, while
also improving performance and memory usage.
Also fixes#3070.
