This reverts commit 52621307bcab2013e8833f3317cebd63a6db3885.
Tests have been failing all night with
[0/2] ACTION //llvm/test:check-llvm(//llvm/utils/gn/build/toolchain:unix) -- Testing: 33647 tests, 64 threads -- Testing: 0 .. 10.. UNRESOLVED: LLVM :: CodeGen/AMDGPU/GlobalISel/isel-blendi-gettargetconstant.ll (6943 of 33647) ******************** TEST 'LLVM :: CodeGen/AMDGPU/GlobalISel/isel-blendi-gettargetconstant.ll' FAILED ******************** Test has no run line! ********************
Since there were other concerns on https://reviews.llvm.org/D67785,
I'm just reverting for now.
