[X86] getTargetConstantBitsFromNode - early-out if the element bitsize doesn't align with the source bitsize (#150184)
As we use getTargetConstantBitsFromNode in a wider variety of places we can't guarantee that all the sources match (or are legal) anymore - better to early out than assert. Fixes #150117
