[TableGen][AMDGPU] R600 DFA packetizer is not deterministic

While enabling the [AMDGPU target](https://codeberg.org/stagex/stagex/pulls/1739) in LLVM container in [StageX](https://stagex.tools/) - a Linux distribution/toolchain focused on bootstrapable and deterministic builds - we noticed that it produced different hashes across different machines.

While analyzing the difference between the resulting binaries with diffoscope, we noticed the following differences, pointing out non-determinism of R600 objects:

The full diff has over 600 MB, but I can try to upload it somewhere if needed.

Start by reproducing the nondeterministic AMDGPU build and inspect the R600 DFA packetizer and the generated R600InstrInfo.cpp.o differences described in the issue. Compare outputs across machines to identify the ordering source; done means producing identical R600 objects and hashes across builds, with a regression test if the relevant test location is found.
