Corinna Vinschen 7666b3634b Cygwin: Fix x86_64 memcpy/memset for n > 2GB
https://cygwin.com/ml/cygwin/2015-07/msg00344.html:

	RtlFillMemory and RtlCopyMemory only work for size values
	up to 2GB.  Fix this problem by using NetBSD code for
	memset and memcpy.  Add entry points for memmove, wmemset,
	wmemmove, wmemcpy.  Thanks to Roman Petrovski
	<RPetrovski@illumina.com> for pointing this out.

        * miscfuncs.cc (memset): x86_64 only: Implement in assembler.
        (memmove,memcpy): x86_64 only: Ditto.
        (wmemmove,wmemcpy): x86_64 only: Ditto.
