6579e48417 Introduced BIND_STATIC opcode instead of FETCH_R/FETCH_W(static)+ASSIGN/ASSIGN_REF (similar to BIND_GLOBAL).
In the future we may refer to static variable by index instead of name, to eliminate hash lookup.

65e456f364 Introduce BIND_LEXICAL
This opcodes inserts a local CV into the closure static variable
table. This replaces the previous mechanism of having static
variables marked as LEXICAL, which perform a symtable lookup
during copying.

This means a) functions which contain closures no longer have to
rebuild their symtable (better performance) and b) we can now track
used variables in SSA.

88eae43ff9 Remove uses of VARs in extended_value
The DECLARE_(ANON_)INHERITED_CLASS(_DELAYED) opcodes were
referencing the parent ce VAR through extended_value. This is
hacky and we can't track the def-use chain in SSA.

To avoid this, the layout of declaration opcodes is changed
as follows: op1 points to the lcname and rtd_key literals, in
that order. (For anon/lambda declarations only one of lcname or
rtd_key is present.) This frees up op2, which is now used to
reference the parent ce VAR in inheriting declarations. The
jmp offset for anon class declarations is moved frop op2 to
extended_value.

The changes were applied both to class and function declarations
to keep everything symmetric.

eb7be5379d Speed up fetching of class entries for self:: parent:: and static::
This is generalized solution for Bob's idea of speed up self::method() calls without ZEND_FETCH_CLASS.

At first, it adds few new opcodes to separate class related behaviour:
	FETCH_STATIC_PROP_R
	FETCH_STATIC_PROP_W
	FETCH_STATIC_PROP_RW
	FETCH_STATIC_PROP_FUNC_ARG
	FETCH_STATIC_PROP_UNSET
	FETCH_STATIC_PROP_IS
	UNSET_STATIC_PROP
	ISSET_ISEMPTY_STATIC_PROP
	FETCH_CLASS_CONSTANT

At seconds, it enables IS_UNUSED operand to fetch (self, parent or static without separate FETCH_CLASS) for new opcodes and the following ones:
	INIT_STATIC_METHOD_CALL
	NEW
	END_INSTANCEOF

Finaly, opcache optimizer had to be fixed to support new opcodes.

commit 4638f7b914
Author: Dmitry Stogov <dmitry@zend.com>
Date:   Wed Jan 28 07:43:28 2015 +0300

    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)

06103d65b1 Use zval_ptr_dtor_nogc() to free IS_TMP_VAR operands.
Removed ZEND_SWITCH_FREE opcode (ZEND_FREE used instead).

de306e7088 Implement call_user_func() and call_user_func_array() using special opcodes.
In some rare cases it leads to insignificant changes in error messages.

b7715c7e8a 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.
