This was originally reported as part of
https://issuetracker.google.com/129895920, where the invalid encoding was
generated by ART. There is a FIXME in
https://github.com/llvm/llvm-project/blob/master/llvm/lib/Target/ARM/AsmParser/ARMAsmParser.cpp#L6419
about this missing case (as well as one for Rm == PC).
