Backported (GPL2) patch to add some sse3 types

>From the FreeBSD log that served as the base for this Bug report:

Backport svn r124339 from gcc 4.3 and add opteron-sse3, athlon64-sse3
and k8-sse3 cpu-types for -march=/-mtune= gcc options.
These new cpu-types include the SSE3 instruction set that is supported
by all newer AMD Athlon 64 and Opteron processors.
All three cpu-types are supported by clang and all gcc versions
starting with 4.3 SVN rev 124339 (at that time GPLv2 licensed).
