New_x86_x64_memsets

Hi, in the following of the bug 16830, I propose here 2 memsets codes for x86
(SSE) and x86-64 architectures.
I have spent 2 months and test more than 100 differents versions of memsets, in
order to find the best for the old and new architectures.
I could post some graphical results in some architectures, from Intel Core2 to
Haswell, and for some AMD CPUs.
All is in the attachment.
