Jan Beulich 9d8e22777e x86-64: Handle byte-wise tail copying in memcpy() without a loop 
While hard to measure, reducing the number of possibly/likely
mis-predicted branches can generally be expected to be slightly
better.

Other than apparent at the first glance, this also doesn't grow
the function size (the alignment gap to the next function just
gets smaller).
