I'm not sure if the problem can be reproduced using a TableGen test.
TableGen processes the .td file without any error and generates incorrect
enum declaration in *InstrInfo.inc file. The problem shows up when we
compile a .cpp file that includes *InstrInfo.inc. In order to reproduce the
problem using a TableGen test, I will have to run it with -gen-instr-info
flag to output this enum declaration.
