Remove REG_PAIR.

I added REG_PAIR in cfbc537 to speed up the register allocator,
because ncg was taking about 2 seconds on each sti 8.  I defined only
4 such pairs, so allocating REG_PAIR was much faster than allocating
REG REG.

After my last commit c5bb3be, allocation of REG REG is fast, and
REG_PAIR seems unnecessary.
