forwprop: change optimize_aggr_zeroprop and optimize_agr_copyprop to take stmt instea...

As mentioned, optimize_aggr_zeroprop and optimize_agr_copyprop don't change the stmt
so they should take stmt instead of the iterator.

Pushed as obvious after bootstrap/test on x86_64-linux-gnu.

gcc/ChangeLog:

	* tree-ssa-forwprop.cc (optimize_aggr_zeroprop): Take gimple*
	instead of iterator.
	(optimize_agr_copyprop): Likewise.
	(simplify_builtin_call): Update call to optimize_aggr_zeroprop.
	(pass_forwprop::execute): Update calls to optimize_aggr_zeroprop
	and optimize_agr_copyprop.
