Simon Pilgrim b4c2d312b7 [DAG] SimplifyMultipleUseDemandedBits - drop unnecessary *_EXTEND_VECTOR_INREG cases
For little endian targets, if we only need the lowest element and none of the extended bits then we can just use the (bitcasted) source vector directly.

We already do this in SimplifyDemandedBits, this adds the SimplifyMultipleUseDemandedBits equivalent.
