FS#6528 - ARM optimised memcpy/memmove
This patch adds the ARM optimised memcpy and memmove functions from glibc. It is almost a verbatim copy, with just a couple of changes to make it compile under Rockbox.
It increases the core size by nearly 1k, but I saw the CPU boost when playing MP3s on my 3G iPod drop below 100% for the first time ever with this patch.
