Hello.
In the v2 of the patch, I tried to address some concerns, raised by Siarhei
Siamashka.
One that I was not sure of how to treat was the vec_perm within splat_alpha
function. It does not look all pretty, but it will work regardless of the
endianness.
Although it was suggested that I created a function that might have performed
the unpacking by itself, I thought that maybe performing the operation while
unpacking could save some lines of code and function calls. Thus I just
replaced that part as you will see in the patch.
I also ran lowlevel-blt-bench with over_8888_8888 and the results (comparing
unpatched and patched) were quite similar.
Please let me know if you have any comments.

Thanks.
