I've ran into same problem. Disabled mesa's llvm use flag temporarily and that made my system usable for the time being.
Comment on attachment 269003 [details] Xorg.0.log on working system. Why don't you attach a build log that shows the failure you are experiencing?
Same with xorg-server-1.10.0.902 getting back to llvm 2.8 (and recompiling mesa just in case) solved the issue. Maybe it would be a good idea to mask llvm 2.9 ?
If you simply run X from the command line the error is more clear: prog: Unknown command line argument '-disable-mmx'. Try: 'prog -help' prog: Did you mean '-disable-lsr'? This is caused by https://bugs.freedesktop.org/show_bug.cgi?id=32564 which is fixed in mesa svn.
xorg-server successfull start with gallium & patch from bugs.freedesktop.org .
