[X86] Exclude invalid element types for bitcast/broadcast folding.
It looks like the fold introduced in 63f3383ece25efa can cause crashes
if the type of the bitcasted value is not a valid vector element type,
like x86_mmx.
To resolve the crash, reject invalid vector element types. The way it is
done in the patch is a bit clunky. Perhaps there's a better way to
check?
