trailing whitespace removal

Use special flag (HASH_FLAG_INITIALIZED) instead of (nTableMask == 0) to indicate that HashTable is allocated.
Make nTableMask to be 0 for packed arrays.
Remove checks fo HASH_FLAG_PACKED in

Use special flag (HASH_FLAG_INITIALIZED) instead of (nTableMask == 0) to indicate that HashTable is allocated.
Make nTableMask to be 0 for packed arrays.
Remove checks fo HASH_FLAG_PACKED in zend_hash_find/zend_hash_del and family (string keys are resolved through uninitialized_bucket).
Change HashTable layout for better locality.

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

first shot remove TSRMLS_* things

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*.

Copy all the arena allocated data from SHM to process memory at once

Opcache compatibility for coalesce operator

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)

We don't need to check for xlat entry twice

Fixed GC problem (arrays may be recorded as possible root of garbage cycle. we have to clear this info before deleting array)

Fixed uint32_t overflow

Fix typo

Update opcache for new AST structures

Remove old version PHP supports

Fixed bug #67725 (now we create immutable arrays only in SHM)

Don't waste SHM for unused Buckets

Removed EG(in_execution). If EG(currentent_execute_data) is not NULL we are executing something.
