<pre>This (<a href="https://godbolt.org/g/EibFPf">https://godbolt.org/g/EibFPf</a>)
declare <8 x i16> @llvm.aarch64.neon.sminp.v8i16(<8 x i16>, <8 x i16>);
define <8 x i16> @vpminq_s16(<8 x i16> %a) {

ret <8 x i16> %b
}
fails to select:
LLVM ERROR: Cannot select: intrinsic %llvm.aarch64.neon.sminp

I am trying to use from LLVM-IR the vpminq_s16 intrinsic which is an AArch64
intrinsic that maps to SMINP Vd.16B,Vn.16B,Vm.16B
