Removed HashTable->arHash (reduced memory consumption). Now hash slots may be accessed using HT_HASH() macro.
Hash slotas are allocated together with Buckets (before them) and lay in reverse order from HashTable->arData base address (see comments in Zend/zend_types.h)
Indexes in hash table and conflict resolution chains (Z_NEXT) may be stored as indeces or offsets in bytes, depending on system (32 or 64-bit).
HashTable data filelds are reordered to keep the most useful for zend_hash_find() data in the same CPU cache line.
This is disabled by default yet, but may be enabled compiling zend_execute.c with -DHAVE_GCC_GLOBAL_REGS.
Only tested on Linux x86 and x86_64 with GCC 4.9.2.

Now each HashTable is also zend_array, so it's refcounted and may be a subject for Copy on Write
zend_array_dup() was changed to allocate and return HashTable, instead of taking preallocated HashTable as argument.

Change "foreach" statement behavior (this is just a PoC yet)
- "foreach by value" don't relay on internal array/object pointer and doesnt perform array duplication. It just locks it incrementing reference counter. If the original array is modified by some code, the copy on write is performed and "foreach" still work with the old copy.
- it makes no difference if array given to "foreach by value" is reference itself
- "foreach by reference" still use internal array/object pointer and should work similar to PHP-5. (This id not completely implemented)
* 'internal-function-return-types' of github.com:reeze/php-src:
Add load time return type checking to match user land logic
Add test function arguments
Implemented internal function return types
