This patch removed some workarounds that were required for old versions
of the LLVM assembler. The minimum supported version is now 13.0.1 so
the workarounds are no longer needed.

amdgcn: remove obsolete assembler workarounds
This nonsense is no longer required, now that the minimum supported
assembler version is LLVM 13.0.1.
gcc/ChangeLog:
* config/gcn/gcn.md (*movbi): Remove assembler bug workarounds.
(jump): Likewise.
(movdi_symbol_save_scc): Likewise.
