65e456f364 Introduce BIND_LEXICAL 
This opcodes inserts a local CV into the closure static variable
table. This replaces the previous mechanism of having static
variables marked as LEXICAL, which perform a symtable lookup
during copying.

This means a) functions which contain closures no longer have to
rebuild their symtable (better performance) and b) we can now track
used variables in SSA.

88eae43ff9 Remove uses of VARs in extended_value 
The DECLARE_(ANON_)INHERITED_CLASS(_DELAYED) opcodes were
referencing the parent ce VAR through extended_value. This is
hacky and we can't track the def-use chain in SSA.

To avoid this, the layout of declaration opcodes is changed
as follows: op1 points to the lcname and rtd_key literals, in
that order. (For anon/lambda declarations only one of lcname or
rtd_key is present.) This frees up op2, which is now used to
reference the parent ce VAR in inheriting declarations. The
jmp offset for anon class declarations is moved frop op2 to
extended_value.

The changes were applied both to class and function declarations
to keep everything symmetric.

eb7be5379d Speed up fetching of class entries for self:: parent:: and static:: 
This is generalized solution for Bob's idea of speed up self::method() calls without ZEND_FETCH_CLASS.

At first, it adds few new opcodes to separate class related behaviour:
	FETCH_STATIC_PROP_R
	FETCH_STATIC_PROP_W
	FETCH_STATIC_PROP_RW
	FETCH_STATIC_PROP_FUNC_ARG
	FETCH_STATIC_PROP_UNSET
	FETCH_STATIC_PROP_IS
	UNSET_STATIC_PROP
	ISSET_ISEMPTY_STATIC_PROP
	FETCH_CLASS_CONSTANT

At seconds, it enables IS_UNUSED operand to fetch (self, parent or static without separate FETCH_CLASS) for new opcodes and the following ones:
	INIT_STATIC_METHOD_CALL
	NEW
	END_INSTANCEOF

Finaly, opcache optimizer had to be fixed to support new opcodes.

Anatol Belski
ffb5d0aca3 Implemented file_cache_fallback mechanism 
which is essential as an attempt to fix the "failed to reattach"
error on Windows. If file_cache is enabled, Opcache will
automaticaly switch to file_cache_only mode in the case a process
failed to map the shared segment at the required address. The
important small part of the SHM will still be mapped, which
allows information exchange between normal processes using SHM
and those using the fallback mechanism.

This is based on Dmitry's, Matt's and mine ideas. So many thanks for
support!

669f0b39b1 Added an experemental ability to move PHP code pages (PHP TEXT segment) into HUGE pages. 
PHP should be configured and built with --enable-huge-code-pages, OS should be configured to provide huge pages.
It's possible to enable/disable this future in php.ini through opcache.enable_huge_code_pages=0/1.
The feature was tested on Linux and provided 2% improvement on real-life apps, because of 2-3 times reduction in number of iTLB misses.

68185bafbe opcache: Patch SSE based fast_memcpy() implementation 
Use _mm_store_si128() instead of _mm_stream_si128(). This ensures that copied memory
is preserved in data cache, which is good as the interpretor will start to use this
data without the need to go back to memory. _mm_stream* is intended to be used for
stores where we want to avoid reading data into the cache and the cache pollution;
in our scenario it seems that preserving the data in cache has a positive impact.

Tests on WordPress 4.1 show ~1% performance increase with fast_memcpy() in place
versus standard memcpy() when running php-cgi -T10000 wordpress/index.php.

I also updated SW prefetching on target memory but its contribution is almost negligible.
The address to be prefetched will be used in a couple of cycles (at the next iteration)
while the data from memory will be available in >100 cycles.
