KVM: PPC: Add helpers to call FPU instructions
To emulate paired single instructions, we need to be able to call FPU operations from within the kernel. Since we don't want gcc to spill arbitrary FPU code everywhere, we tell it to use a soft fpu. Since we know we can really call the FPU in safe areas, let's also add some calls that we can later use to actually execute real world FPU operations on the host's FPU.
