Ahmed Bougacha 27eebc518c [X86] Extract PSIGN/BLENDVP tests into vector-blend.ll. NFC.
We're going to stop generating PSIGN, so calling a test "psign"
isn't ideal. Instead, call these tests what they really are:
variable blends using logic.
Also add a test to exhibit a case we're currently missing in
the PSIGN combine.
