2c1442e1b2 Be more strict when detecting critical edges before loop splitting. 
An exit block with a critical edge must only have predecessors in the loop, or
just before the loop. This guarantees that the inserted copies in the loop
predecessors dominate the exit block.

d451f888b8 ARM encodes Q registers as 2xregno (i.e. the number of the D register that corresponds to the lower 
half of the Q register), rather than with just regno.  This allows us to unify the encodings for
a lot of different NEON instrucitons that differ only in whether they have Q or D register operands.
