This series fixes an issue which David Spickett found where if we change the SVE VL while SME is in use we can end up attempting to save state to an unallocated buffer and adds testing coverage for that plus a bit more coverage of VL changes, just for paranioa.

Applied to arm64 (for-next/selftests), thanks!
