CVS commit: src/common/lib/libc/arch/x86_64/string
Module Name: src
Committed By: dsl

Align to the destination buffer.
This probably costs 1 clock (on modern cpus) in the normal case.
But gives a big benefit when the destination is misaligned.
In particular when the source has the same misalignment - although
that may not be a gain on Nehalem!
