Improved access to static property. Now we cache pointers to zval instead of pointers to property_info.

trailing whitespace removal

Don't count variadic argument in zend_func.common.num_args. This allows faster CALL/RETURN code.

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.

Use zend_string* for op_array->arg_info[]->name and op_array->arg_info[]->class_name. For internal functions we still use char*.

Revert "Unecessary assignment"

This reverts commit b19333663a872a8b0b8c799781236b5cd5bfa47a.

Unecessary assignment

Rename EX_VAR_2() into ZEND_CALL_VAR() and EX_VAR_NUM_2() into ZEND_CALL_VAR_NUM().

Changed "finally" handling. Removed EX(fast_ret) and EX(delayed_exception). Allocate and use additional IS_TMP_VAR slot on VM stack instead.

bring back all the TSRMLS_FETCH() stuff

for better comparability with the mainstream

cleanup TSRMLS_FETCH

Allocate copies of internal functions inherited in user classes at CG(arena), instead of permanent heap (malloc).

Initial coalesce operator implementation

fix signed/unsigned mismatch

Removed ZEND_QM_ASSIGN_VAR and ZEND_JMP_SET_VAR opcodes (in PHPNG they did exacly the same as ZEND_QM_ASSIGN and ZEND_JMP_SET)

Use zval_ptr_dtor_nogc to destroy literals

Also move the definition of zval_ptr_dtor_nogc to zend_variables.h
(from zend_execute.h/.c) as it's used in a few places.

Reorder fields for better nenory consumtion and data locality on 64-bit systems

Use efree_size() instead of efree() where posible

Remove ZEND_ACC_INTERACTIVE and CG(interactive)

As far as I can discern these are leftovers of the interactive
shell implementation that was used before PHP 5.4. Now the readline
ext

Remove ZEND_ACC_INTERACTIVE and CG(interactive)

As far as I can discern these are leftovers of the interactive
shell implementation that was used before PHP 5.4. Now the readline
ext makes use of normal eval calls for this.

So, dropping these until there is evidence to the contrary, as they
currently wouldn't work anyway.
