[patch] Fix new string2.h optimization

[Ben Collins <bcollins at debian dot org>]

The new optimization does this for __memcpy:

	__builtin_memcpy (dest, src, n) + n

But like in gconv_conf.c, it is used sometimes like this:

	char *to, *from;
	....
	memcpy(dest, src, to - from);

This patch fixes that:

	* string/bits/string2.h: __mempcpy(): Protect size arg for
	addition when using __builtin_memcpy.
