i#899 win8+ syscalls: handle NtSetInformationVirtualMemory
i#899 win8+ syscalls: handle NtSetInformationVirtualMemory

DR doesn't need to take action on the 2 uses of the new syscall
NtSetInformationVirtualMemory (called from KERNELBASE!PrefetchVirtualMemory
and from KERNELBASE!SetProcessValidCallTargets) so we remove the NYI check
from the code.
