I did the first pass and added some questions/clarifications and minor suggestions.

Wondering why don't we do something like else below i.e. call findAnotherHalfRegRec() instead of getSecondHalfRegRec()? Do things vary if assignedInterval's registerType == TYP_DOUBLE ?

The comment of this method always expect reg to be lower half: "reg" should be a even-numbered float register, i.e. lower half of double register.
Perform register allocation for a given RefPosition with a single traversal of the registers, whether free or busy.
Fix one source of arm32 double diffs.
Fix `nextPhysRefLocation` computation for Arm32

Combine register selection to consider free and busy registers in the same method.
Refactor the selection to make it easier to reorder the criteria.
