Switch the NEON register class from QPR to DPair.
The already allocatable DPair superclass contains odd-even D register
pair in addition to the even-odd pairs in the QPR register class. There
is no reason to constrain the set of D register pairs that can be used
for NEON values. Any NEON instructions that require a Q register will
automatically constrain the register class to QPR.
The allocation order for DPair begins with the QPR registers, so
register allocation is unlikely to change much.
