14 years agoReplace a big gob of old coalescer logic with the new CoalescerPair class.

Replace a big gob of old coalescer logic with the new CoalescerPair class.

CoalescerPair can determine if a copy can be coalesced, and which register gets
merged away. The old logic in SimpleRegisterCoalescing had evolved into
something a bit too convoluted.
