ZEND_ADD_STRING/VAR/CHAR are replaced with ZEND_ROPE_INTI, ZEND_ROPE_ADD, ZEND_ROPE_END.
Instead of reallocation and copying string on each ZEND_ADD_STRING/VAR/CAHR, collect all the strings and then allocate and construct the resulting string once.
a) The SAME_FAKE_TYPE check should always occur on the dereferenced
value, otherwise we'll end up separating large referenced arrays.
b) For by-val return with an rc=1 reference, the SEPARATE_ZVAL
wouldn't do anything. Add a ZVAL_UNREF for this case.
I don't like this fix - there must be some better way to express
this.
EX_PREV_USES_STRICT_TYPES() and family changed/renamed to fit with other macros
Optimized zend_verify_internal_arg_type() and family (they don't need "strict" argument anymore)
Standerd ZPP is called from VM only for weak type check or strict exception (int -> double)
Fixed ZEND_RECV_VARIADIC
Fixed ZEND_STRLEN
TODO: should we accept IS_NULL for non-nullable arguments?
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.

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
- predcalculate offsets of passed argument and store it in opline->result.var for ZEND_SEND_*;
- don't update "number of passed arguments" op each ZEND_SEND_* opcode, store it on call frame creation
- Change ZEND_HANDLE_EXCEPTION to determine "number of passed arguments" in incomplete calls fefore freeing

small fixes to UPGRADING
Reorder to save alignment size (of course, only for common used structs)
the main idea - the smaller the zend_op structure, the lees memory traffic is required to load VM instructions during execution. The patch reduces the size of each opcode from 48 to 32 bytes (saves 16 bytes for each opcode, and applications use thousands of opoceds). This reduced the number of CPU cache misses by 12% and improved performance of real-life apps by 1-2%.
The patch affects how constants and jump targets are represented in VM during execution. Previously they were implemented as absolute 64-bit pointers. Now they are relative 32-bit offsets.
In run-time constant now should be accessed as:
RT_CONSTANT(op_array, opine->op1) instead of opline->op1.zv
EX_CONSTANT(opline->op1) instead of opline->op1.zv
Jump targets:
OP_JMP_ADDR(opline, opline->op2) instead of opline->op2.jmp_addr
The patch doesn't change zend_op representation for 32-bit systems. They still use absolute addresses. The compile-time representation is also kept the same.
I thought these SEPARATE_ZVAL_IF_NOT_REF usages were safe at first,
because incdec op supports reference variables. However this
violates the constraint that IS_TMP_VAR variables may not be
references (which is an issue if you use the result of the incdec
op).
Still need to fix the cases where read_property/write_property is
used.

Fix nesting for *non*-compile-time-resolveable functions See a1a4ba9511 (commitcomment-7414223)
Add tests for calls to nested, *non*-compile-time-resolveable functions See a1a4ba9511 (commitcomment-7414362)
Make list of opcodes used for nesting calculation consistent with `zend_do_convert_call_user_func()` in Zend/zend_compile.c
Rewrite code to use ZEND_VM_JMP() instead of repeated ZEND_VM_INC_OPCODE() calls
QA: Simplify code to find matching ZEND_DO_FCALL_BY_NAME CG(context).nested_calls is stored inside the initializer's result.num and inside the finalizer's op2.num, by comparing these we don't need to count manually, and are thus safer from future expansion with specialized opcodes e.g.
Fix expected fatal error, now is catchable fatal
Adjust expected fatal error message Now also includes "on [TYPE]" after merge from master
