Parallel Move Resolver: Perform Stack/Stack first
On machines like x86, by the time other parallel moves are done, there
may be no free registers available to move/swap without having to save
and restore a register.
To avoid this, perform stack/stack first, while there is a good chance
that there is a destination register that we can use. On the X86, this
avoids a lot of push eax/pop eax code.
