Simon Pilgrim 04933872c3 [InstCombine][SSE] Add MOVMSK support to SimplifyDemandedUseBits 
The MOVMSK instructions copies a vector elements' sign bits to the low bits of a scalar register and zeros the high bits.

This patch adds MOVMSK support to SimplifyDemandedUseBits so that its aware that the upper bits are known to be zero. It also removes the call to MOVMSK if none of the lower bits are actually required and just returns zero.
