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.

    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).
