This change is part of this proposal: https://discourse.llvm.org/t/rfc-all-the-math-intrinsics/78294 This preliminary work adds the intrinsic to llvm and expands using atan intrinsic for DXIL backend, since DXIL has no atan2 op. Part 1 for Implement the atan2 HLSL Function #70096. (reland #108865 reverted in #109842 due to doc build break)
