phiopt: Move check for maybe_undef_p slightly earlier

This moves the check for maybe_undef_p in match_simplify_replacement
slightly earlier before figuring out the true/false arg using arg0/arg1
instead.
In most cases this is no difference in compile time; just in the case
there is an undef in the args there would be a slight compile time
improvement as there is no reason to figure out which arg corresponds
to the true/false side of the conditional.

Bootstrapped and tested on x86_64-linux-gnu.

gcc/ChangeLog:

	* tree-ssa-phiopt.cc (match_simplify_replacement): Move
	check for maybe_undef_p earlier.
