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.
