Fix gcc.target/aarch64/simd/vmulxd_{f64,f32}_2.c after after IPA-VRP improvement for return values

Just like the patch against gcc.target/aarch64/movk.c, the issue here
is the two functions, foo32 and foo64 needed to mark as noipa so that
IPA-VRP cannot propagate the return value.

gcc/testsuite/ChangeLog:

	PR testsuite/112688
	* gcc.target/aarch64/simd/vmulx.x (foo32): Mark as noipa rather
	than noinline.
	(foo4): Likewise.
