This patch utilizes the helper function implemented in D149699 and thus folds the following cases: ``` bitreverse(logic_op(x, bitreverse(y))) -> logic_op(bitreverse(x), y) bitreverse(logic_op(bitreverse(x), y)) -> logic_op(x, bitreverse(y)) bitreverse(logic_op(bitreverse(x), bitreverse(y))) -> logic_op(x, y) in multiuse case ``` Reviewed By: goldstein.w.n, RKSimon Differential Revision: https://reviews.llvm.org/D151246
