[PATCH] D149049: [AMDGPU][Disassembler] Fix a spurious error message in an instruction comment.

[Ivan Kosarev via Phabricator via llvm-commits]

kosarev added a comment.

Note that with the change in place no comments passed to `AMDGPUDisassembler::errOperand()` may ever be visible to the user, because that function returns a default-constructed `MCOperand`, which is considered invalid by `addOperand()` defined in `AMDGPUDisassembler.cpp` and so instructions having such operands will always be seen as failed decoding attempts. To expose the error messages we would need to support erroneous operands as the comment in `AMDGPUDisassembler::errOperand()` proposes or find another way.
