[SelectionDAG] BITREVERSE vector legalization of bit operations (REAPPLIED)
Some vector bit operations are promoted instead of having custom lowering. This patch changes the isOperationLegalOrCustom tests for vector AND/OR operations to use a new TLI helper isOperationLegalOrCustomOrPromote instead, allowing the SSE implementations to stay on the simd unit.
