[DAGCombiner] Fold step_vector with add/mul/shl This patch implements some DAG combines for STEP_VECTOR: add step_vector(C1), step_vector(C2) -> step_vector(C1+C2) add (add X step_vector(C1)), step_vector(C2) -> add X step_vector(C1+C2) mul step_vector(C1), C2 -> step_vector(C1*C2) shl step_vector(C1), C2 -> step_vector(C1<<C2) TestPlan: check-llvm Differential Revision: https://reviews.llvm.org/D100088 GitOrigin-RevId: 7e1422c1e43023e4cd5fbb3305f8dbf2d626e87e
