KVM: x86: Reduce the number of emulator GPRs to '8' for 32-bit KVM
Reduce the number of GPRs emulated by 32-bit KVM from 16 to 8. KVM does
not support emulating 64-bit mode on 32-bit host kernels, and so should
never generate accesses to R8-15.
Opportunistically use NR_EMULATOR_GPRS in rsm_load_state_{32,64}() now
that it is precise and accurate for both flavors.
Wrap the definition with full #ifdef ugliness; sadly, IS_ENABLED()
doesn't guarantee a compile-time constant as far as BUILD_BUG_ON() is
concerned.
