PHIOPT: small cleanup in match_simplify_replacement

We know that the statement we are moving is already
have a SSA_NAME on the lhs so we don't need to
check that and can also just call reset_flow_sensitive_info
with the name we already got.

OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.

gcc/ChangeLog:

	* tree-ssa-phiopt.cc (match_simplify_replacement):
	Simplify code that does the movement slightly.
