2012-09-10	reenable word-at-at-time copying in memmove	Rich Felker	-4/+27
	before restrict was added, memove called memcpy for forward copies and used a byte-at-a-time loop for reverse copies. this was changed to avoid invoking UB now that memcpy has an undefined copying order, making memmove considerably slower. performance is still rather bad, so I'll be adding asm soon.
2012-09-06	remove dependency of memmove on memcpy direction	Rich Felker	-5/+4
	this commit introduces a performance regression in many uses of memmove, which will need to be addressed before the next release. i'm making it as a temporary measure so that the restrict patch can be committed without invoking undefined behavior when memmove calls memcpy with overlapping regions.
