RE: [PATCH, i386]: AMD bdver3 enablement


Hi Uros!

> sseshuf replaces sselog in some insn patterns, but should be handled in the same way in *existing* .md files.

Modifications done as per the comments. 
1. Sseshuf is added along with sselog in existing md files.
2. sseshuf is handled in a separate pattern in bdver3.md

Bootstrapping and "make -k check" passes.
Ok for trunk?

Regards
Ganesh

sseshuf replaces sselog in some insn patterns, but should be handled in the same way in *existing* .md files.
