Implement double and float support for arm in register allocator.
The basic approach is:
- An instruction that needs two registers gets two intervals.
- When allocating the low part, we also allocate the high part.
- When splitting a low (or high) interval, we also split the high
(or low) equivalent.
- Allocation follows the (S/D register) requirement that low
registers are always even and the high equivalent is low + 1.
