Heejin Ahn d20d0648ed [DAGCombiner] Fix a case of 1 in non-splat vector pow2 divisor ... Summary: D42479 (rL329525) enabled SDIV combine for pow2 non-splat vector dividers. But when there is a 1 in a vector, the instruction sequence to be generated involves shifting a value by the number of its bit widths, which is undefined (c64f4dbfe3/lib/CodeGen/SelectionDAG/DAGCombiner.cpp (L6000-L6006)). Especially, in architectures that do not support vector instructions, each of element in a vector will be computed separately using scalar operations, and then the resulting value will be undef for '1' values in a vector. (All 1's vector is fine; only vectors mixed with 1 and others will be affected.)
