[SelectionDAG] Add basic demanded elements support to ComputeNumSignBits for BITCAST nodes 

Only adds support to the existing 'large element' scalar/vector to 'small element' vector bitcasts.

The next step would be to support cases where the large elements aren't all sign bits, and determine the small element equivalent based on the demanded elements.
