Reimplemented silence operator (@) handling on exceptions. Now each silence region is stored in op_array->brk_cont_array. On exception ZEND_HANDLE_EXCEPTION handler traverse this array and restore original EG(error_reporting) if exception occured inside a "silence" region.

Fixed list() behavior inconsistency (string handling is disabled for all cases, ArrayAccess objects handling is enabled for all cases, ZEND_FETCH_DIM_TMP_VAR opcode is renamed into ZEND_FETCH_LIST, ZEND_FETCH_ADD_LOCK flag is removed).

Drop unused INIT_STRING opcode

INIT_STRING has been implemented as an UNUSED op1 to ADD_* for
some time now.

Opcache compatibility for coalesce operator

Use zval_ptr_dtor_nogc() to free IS_TMP_VAR operands.
Removed ZEND_SWITCH_FREE opcode (ZEND_FREE used instead).

Fixed typo

Fixed useless or duplicated IS_INTERNED() checks

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)

Refactored optimizer (compile different opimizer passes separately, instead of including *.c file)

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

master renames phase 2

master renames phase 1

basic macro replacements, all at once

Refactored parameter passing mechanism.

In PHP-5.6 and below each argument passed to user function was copies on VM stack twice.
Now we always have ZEND_INIT_FCALL (or simular) opcode that pushes "call frame" on top of VM stack.
"Call frame" is actually the same zend_execute_data structure.
All the following ZEND_SEND instructions push arguments on top of the stack in a way that they directly comes into corresponding CV variables of the called frame. Extra arguments are copied at the end of stack frame (after all CV and TMP variables) on function enterance.

There are two minor incompatibilities:
1) It's not allowed to decalre functions redefining arguments e.g. "function foo($a,$a) {}".
2) func_get_arg() and func_get args() return the current value of argument and not the original value that was sent.

Fixed new hash API usage
