[DAGCombiner] Allow visitEXTRACT_SUBVECTOR to combine with BUILD_VECTORS... 

[DAGCombiner] Allow visitEXTRACT_SUBVECTOR to combine with BUILD_VECTORS between LegalizeVectorOps and LegalizeDAG.

BUILD_VECTORs aren't themselves legalized until LegalizeDAG so we should still be able to create an "illegal" one before that. This helps combine with BUILD_VECTORS that are introduced during LegalizeVectorOps due to unrolling.
