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