The main fix here is on non-AVX builds, the shifts require dst == src.
Calling macro-assembler functions like Psrlw assumes that we already
met that requirement (which we usually specify in TurboFan's
instruction-selector). On Liftoff, we need to do that check manually.
This is done by using the helper EmitSimdShiftOpImm which will do this
check, and dispatches to AVX if supported, or mov if dst != src.

Also fix a couple of places where we forgot to annotate the required SSE
extension for the instruction.
