This reverts commit 640beb38e7710b939b3cfb3f4c54accc694b1d30 <https://reviews.llvm.org/rG640beb38e7710b939b3cfb3f4c54accc694b1d30>.

That commit caused performance degradtion in Quicksilver test QS:sGPU and a functional test failure in (rocPRIM rocprim.device_segmented_radix_sort).
Reverting until we have a better solution to s_cselect_b64 codegen cleanup
