This reverts commit 640beb38e7710b939b3cfb3f4c54accc694b1d30. 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 Change-Id: Ifc167b3c2dae7a65920676f22a97ba76485f3456 Reviewed By: kzhuravl Differential Revision: https://reviews.llvm.org/D116686 Change-Id: I1abf49b74a7e2ba0e0205f747a4154a468b9d7f2
