[LLVM] Update to llvm/llvm-project@1f20eee6dc36 (#5308)

This pulls in the AMDGPU backend support for the gfx950 target. We need to fix the rewrites in `Combine.td` given that llvm/llvm-project#112700 adds a new attribute for denorm mode for `arith.addf`. --------- Co-authored-by: Lei Zhang <[email protected]>
