<!--LLVM PR SUMMARY COMMENT-->
@llvm/pr-subscribers-backend-amdgpu
Author: Adam Yang (adam-yang)
<details>
<summary>Changes</summary>
Constructing Target triple with `ObjectFile::makeTriple` instead of just with `Arch` and leaving the rest unknown. Also creating the subtarget with the `CPU`. AMDGPU needs the full triple and `CPU` to disassemble correctly.
To run a full test, also fixed a failure with the `$noreg` operand in `DBG_VALUE`, and writing relocation with `AMDPAL`.
