Yes, that adds FPU support for ARM.

Hmm, whole ARM reg set is missing in this file. IIRC Simon Marlow were 
discussing this with Ben Gamari recently. I've not investigated if this 
is needed or not since I don't know if this is used only in NCG or in 
registerised build in general. If the former, ARM will not be there as 
there is no ARM NCG yet, if the later, then ARM should be there as 
ARM/LLVM/registerised build is a reality.

Cheers,
Karel
