Roman Lebedev 73b691a716 [llvm-exegesis] Fix serialization/deserialization of special NoRegister register (PR41448) ... Summary: A *lot* of instructions have this special register. It seems this never really worked, but i finally noticed it only because it happened to break for `CMOV16rm` instruction. We serialized that register as "" (empty string), which is naturally 'ignored' during deserialization, so we re-create a `MCInst` with too few operands. And when we then happened to try to resolve variant sched class for this mis-serialized instruction, and the variant predicate tried to read an operand that was out of bounds since we got less operands, we crashed. Fixes [[ https://bugs.llvm.org/show_bug.cgi?id=41448 | PR41448 ]].
