Move the folding of memcmpy to memcmpy_eq to fold all builtinsHEADtrunkmaster

This is a small cleanup by moving the optimization of memcmp to
memcmp_eq to fab from strlen pass. Since the copy of the other
part of the memcmp strlen optimization to forwprop, this was the
only thing left that strlen can do memcmp.

Note this move will cause memcmp_eq to be used for -Os too.

It also removes the optimization from strlen since both are now
handled elsewhere.

Bootstrapped and tested on x86_64-linux-gnu.

gcc/ChangeLog:

	* tree-ssa-ccp.cc (optimize_memcmp_eq): New function.
	(pass_fold_builtins::execute): Call optimize_memcmp_eq
	for memcmp.
	* tree-ssa-strlen.cc (strlen_pass::handle_builtin_memcmp): Remove.
	(strlen_pass::check_and_optimize_call): Don't call handle_builtin_memcmp.
