During code motion, a negative value indicates a reg that has
been made a candidate; in particular -2 means that it is an
candidate that we know is equal to a constant and -1 means that
- it is an candidate not known equal to a constant. After code
+ it is a candidate not known equal to a constant. After code
motion, regs moved have 0 (which is accurate now) while the
failed candidates have the original number of times set.
