  Revert "Revert "[AArch64][GlobalISel] Add selection support for <8 x s16>  G_INSERT_VECTOR_ELT with GPR scalar.""

This isn't a real with the codegen, it's a previously known bug in clang which
causes non-deterministic failures due to garbage bits in undef registers being
used in saturating instructions.

I'm disabling the result checking for the test until this issue is resolved.

This reverts commit 6c8168324b5329c94fe7e8f9a1619802091b9bec.
