[llvm] [NFC][AMDGPU] Convert amdpal.ll to autogenerated CHECK lines (PR #141026)

[Matt Arsenault via llvm-commits]

https://github.com/arsenm requested changes to this pull request.

This test cannot be converted to generated checks. The generated checks only include the instructions in the function body, and none of the metadata. This test only really cares about the metadata
