27144f4c - [TableGen] Return int32_t from InstrMapping table lookup functions. NFC. (#182079)

[TableGen] Return int32_t from InstrMapping table lookup functions. NFC. (#182079) Since #182059 there is only one case in which these functions return -1, so callers no longer need to distinguish between (int64_t)-1 and (uint32_t)-1, so we can go back to a 32-bit return value like it was before #180954.
