[TargetLowering] SimplifyMultipleUseDemandedBits - add BITCAST pass through support...

This allows us to peek through BITCASTs, attempt to simplify the source operand, and then bitcast back.

This reapplies rL367091 which was reverted at rL367118 - we were inconsistently peeking through the bitcasts to the source value.

Fixes PR42777
