ARM: Fix reg resolution for doubles

1) When an odd float register becomes free, we may need to add the corresponding (even) double register to `targetRegsReady` (this was the bug)
2) When an even float register becomes free, we can't add it to `targetRegsReady` unless it's other half is also free.
