[X86] Add test showing failure to remove sign splats from PACKSS intrinsics (#161518)
PACKSS intrinsic calls are only expanded to X86ISD::PACKSS nodes during
legalisation, after which time we fail to handle cases where ASHR sign
splats (now lowered to X86ISD::VSRAI) are unnecessary.
Add additional example of FREEZE(PACKSS()) as that's an issue as well.
