This change makes ecma_number_make_nan and ecma_number_make_infinity
always return constant value without any function call. Previously we
relied on compiler optimizations.
The ecma_number_t_accessor union is introduced to be able to access
float values as float and uint32_t (and doubles as double and uint64_t)
properly, without violating strict aliasing rules. There were many
copies of it, all of them were replaced to this new union.
Additionally ecma_number_make_nan should return QNaN instead of SNaN,
same value as C99 nan(""). Unfortunately calling nan("") here isn't
always optimal, because compilers sometimes generate constant returns,
sometimes function calls.
Before this change ecma_number_make_nan returned SNaN:
- double: 0x7FF0 0000 0000 0001 (sign:0, exponent: all 1 bits, fraction: 0...01)
- float: 0x7F8 00001 (sign:0, exponent: all 1 bits, fraction: 0...01)
After this change ecma_number_make_nan returns QNaN:
- double: 0x7FF8 0000 0000 0000 (sign:0, exponent: all 1 bits, fraction: 10..0)
- float: 0x7FC0 0000 (sign:0, exponent: all 1 bits, fraction: 10...0)

The implementation was incorrect for negative years and years bigger than 9999.
-1 was 000/ because the negative (year%10) was added to '0' character, years
bigger than 9999 was truncated to 4 digits.
ES5.1 15.9.1.15.1 defines extended years format with 6 digits, but toString()
and toISOString() sections don't mention anything about extended years. ES6
20.3.4.3 already clarifies that Date.prototype.toISOString() should use this
extended year format if it is necessary.
Changes:
- Date.prototype.toString() uses 4 digits for years by default, 5 or 6 if it
is necessary and put '-' sign for negative years, no sign for positive years.
Date.prototype.toString() was implementation dependent until ES9, but ES9
already specify exactly this format.
- Date.prototype.toISOString() uses fixed 4 digits for years 0 - 9999,
otherwise sign + 6 digits (extended years).
- Tests added for corner cases.

ES5.1 15.9.4.2 specifies that Date.parse (string) has to accept
at least Date Time String Format: YYYY-MM-DDTHH:mm:ss.sssZ. But
the spec allows implementation-specific fallbacks. Additionally
ES5.1 15.9.1.15.1 specifies Extended years format, but isn't
explicitly required to be accepted by Date.parse. But ES6 already
clarified that Date.parse has to accept extended years format too.

We should emit function symbols for these jerry-core functions:
- ecma_compare_ecma_strings is used by test-stringbuilder.c
- ecma_is_value_number is used by test-literal-storage.c
- ecma_date_time_within_day is used by test-date-helpers.c
- jmem_heap_alloc_block is used by test-jmem.c
- jmem_heap_free_block is used by test-jmem.c
- jmem_pools_alloc is used by test-poolman.c
- jmem_pools_free is used by test-poolman.c

Disable 02.API-REFERENCE-create-context.c, because
it is based on pthread, and there is no pthread on Windows.
Disable 11.EXT-REFERENCE-AUTORELEASE.c and test-ext-autorelease.c
if compiler is MSVC, because MSVC doesn't support cleanup attribute.

MSVC doen't support __attribute__((unused)),
we should use JERRY_UNUSED macro instead.
Additionally removed the internal jrt.h include from
tests/unit-core/test-common.h which was layering violation.
It made JERRY_ASSERT unavailable, we should use TEST_ASSERT.

The Math.pow implementation calls libm's pow. The ISO C and ES5.1
standards differ on some special cases of pow. jerry-libm is already
ES5.1 conform, but system libm libraries on Linux and Windows aren't.
Math.pow(NaN, +/-0.0) is NaN on Windows and Linux with system libm,
but should be 1.0 according to ES5.1 / 15.8.2.13.
This patch handles this special case in Math.pow instead of calling pow of libm.
