In order to be able to reuse the save-restore code in KVM, move
it to a pair of macros, similar to what the 32bit code does.

arm64: Floating point and SIMD2012-09-17T12:42:13ZCatalin Marinas2012-03-05T11:49:32Zurn:sha1:53631b54c8704fe5de435582c82ddbc0bfabf06a
This patch adds support for FP/ASIMD register bank saving and restoring
during context switch and FP exception handling to generate SIGFPE.
There are 32 128-bit registers and the context switching is currently
done non-lazily. Benchmarks on real hardware are required before
implementing lazy FP state saving/restoring.
