baf97b1fcc We don't nees zend_op_array->brk_cont_array at run-time anymore. 
Move zend_op_array->brk_cont_array into CG(context).brk_cont_array.
Use more compact zend_op_array->live_range instead of zend_op_array->brk_cont_array.
Semantic is kept unchanged.

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.

517b553625 Fixed bug #70630 (Closure::call/bind() crash with ReflectionFunction->getClosure()) 
This additionally removes support for binding to an unknown (not in parent hierarchy) scope.
Removing support for cross-scope is necessary for certain compile-time assumptions (like class constants) to prevent unexpected results

cff6cbc01f Emit EXT_STMT for each statement 
I'm excluding unticked statements for this (in 5.x they were included)
as this would just result in two consecutive EXT_STMTs.

Also add all class statements to unticked statements, these would
generate superfluous EXT_STMT/TICKS in the parent op_array.

301ee26568 Fixed situation, when CHECH_EXCEPTION() might change value of "opline" variable and the following "opline" useages would access elements of different opcode. That might lead to unpredictable behavior. (Only PHP-7 with GCC global register variables was affected). 
CHECK_EXCEPTION() macro is removed. ZEND_VM_NEXT_OPCODE_CHECK_EXCEPTIO() should be used instead. It's equivalent to old CHECK_EXCEPTION() + ZEND_VM_NEXT_OPCODE().
As a side effect, this also slightly improved performnce of builds with GCC >= 4.8.

brk_cont is compile-time the distinction is no longer necessary.

Also drops brk_cont.start, check the loop_var op_type instead.

    Improved algorithm. It's actually the same algorithm with second loop removed and simpler temporary data structures. The only difference may be in "re-defined" vatriable handling. Now live-range in that case started from the seconnd definition (this must be more safe).
