util/romcc: Prevent out-of-bounds read
If 'class > LAST_REGC', then there will be an out-of-bounds read when accessing 'regcm_bound'. Prevent this by skipping to the next iteration of the loop. Note that this should not generally happen anyway, since 'result' represents a bitset for the indices of 'regcm_bound', and so iterations where 'class > LAST_REGC' should already be skipped by the previous continue statement (since those bits of 'result' should all be zero).
