[X86] movsd/movss/movd/movq - add support for constant comments (#78601)
If we're loading a constant value, print the constant (and the zero upper elements) instead of just the shuffle mask.
This did require me to move the shuffle mask handling into addConstantComments as we can't handle this in the MC layer.
