match: Remove valueize_condition argument from gimple_extra template

After r15-4791-gb60031e8f9f8fe, the valueize_condition argument becomes
unused. I didn't notice that as there was -Wno-unused option being added
while compiling gimple-match-exports.cc. This removes that too as there are
no unused warnings.

gcc/ChangeLog:

	* Makefile.in (gimple-match-exports.o-warn): Remove.
	* gimple-match-exports.cc (gimple_extract): Remove valueize_condition
	argument.
	(gimple_extract_op): Update call to gimple_extract.
	(gimple_simplify): Likewise. Also remove valueize_condition lambda.
