Flip hi/lo to lo/hi in LowerInt64 and related code

Reviewed by Justin Michaud.
AirCCallingConvention allocates registers in order, so passing the low
bits of an Int64 avoids the need to massage things. However, we want to
have a consistent order in all related code to avoid silly mistakes, so
this changes everything other than the assembler to use lo, hi ordering.
