This relands triton-lang#5392 to enable new arch target since backend support has been added--it doesn't depend on the reverted LLVM upgrade in triton-lang#5341; basic necessary enablement is already included in the current llvm version we're using. (cherry picked from commit f257479)

I have "bisected" the current CUDA regression (mentioned [here](#5341)) on A100: ``` git bisect start # bad: [f5a35a31bfe6cbc16bec0c130f2bb3632dbf1fbf] [LV] Add test cases with incorrect IV live-outs. git bisect bad f5a35a31bfe6cbc16bec0c130f2bb3632dbf1fbf # good: [86b69c31642e98f8357df62c09d118ad1da4e16a] [SPIR-V] Fix SPIR-V extension SPV_INTEL_function_pointers: ... # first bad commit: [b8703369daf777706196ff914c0376c27adde3cf] [SLP] Match poison as instruction with the same opcode ``` The failure presents as : ``` Traceback (most recent call last): File "/home/mleventa/dev_projects/repro/repro.py", line 135, in <module> torch.cuda.synchronize() File "/home/mleventa/dev_projects/.venv/lib/python3.10/site-packages/torch/cuda/__init__.py", line 987, in synchronize return torch._C._cuda_synchronize() RuntimeError: CUDA error: an illegal memory access was encountered ``` The failing commit is [`b870336`](llvm/llvm-project#115946) and the last working commit is `2fe947b4`. It's not clear to me the relationship but will investigate. This PR to `llvm-head` is to verify that my repro on A100 matches the internal regression/fail.
