Simon Pilgrim 8ca5ce94d4 [DAG] SimplifyDemandedBits - peek through SHL if we only demand sign bits.
If we're only demanding the (shifted) sign bits of the shift source value, then we can use the value directly.

This handles SimplifyDemandedBits/SimplifyMultipleUseDemandedBits for both ISD::SHL and X86ISD::VSHLI.
