If only one subvector extraction will be necessary (i.e. because the other is constant etc.) then extract the source operands and perform as a 128-bit comparison Ideally DAGCombiner's narrowExtractedVectorBinOp would handle this but its tricky to confirm when a target opcode can be safely extracted and performed as a different vector type Partially improves an outstanding regression in #82290
