JitArm64: Move float conversion code out of EmitBackpatchRoutine

This simplifies some of the following commits. It does require
an extra register, but hey, we have 32 of them.

Something I think would be nice to add to the register cache
in the future is the ability to keep both the single and double
version of a guest register in two different host registers
when that is useful. That way, the extra register we write to
here can be read by a later instruction, saving us from
having to perform the same conversion again.
