[SelectionDAG] Teach LegalizeVectorOps to directly Expand... 

[SelectionDAG] Teach LegalizeVectorOps to directly Expand CTTZ_ZERO_UNDEF/CTLZ_ZERO_UNDEF to CTTZ/CTLZ directly if those ops are Legal/Custom instead of deferring it to LegalizeOps.

This is needed to support CTTZ/CTLZ Custom correctly since LegalizeOps would be too late to do the custom lowering.
