James Hogan 1c0cd66adb MIPS: KVM: Add FP exception handling 
Add guest exception handling for floating point exceptions and
coprocessor 1 unusable exceptions.

Floating point exceptions from the guest need passing to the guest
kernel, so for these a guest FPE is emulated.

Also, coprocessor 1 unusable exceptions are normally passed straight
through to the guest (because no guest FPU was supported), but the
hypervisor can now handle them if the guest has its FPU enabled by
restoring the guest FPU context and enabling the FPU.
