c42ac09518 Added new API function 'zend_string* zend_string_tolower(zend_string*)'. 
It simplifies code and avoids unnecessary allocation and copying if string is already in lower case.

3a18597774 Optimize argument passing handlers: 
- 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

caf5521416 Revert "Removed useless local variable" 
This reverts commit 44ae32ad55.

It doesn't work properly. We can't access call->scope after free.

14e29f5146 Reduced size of zend_op on 64-bit systems. 
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.
