[Mesa-stable] Stable radeon patches for 10.0

[Tom Stellard]

Hi Carl,

Could you apply these 4 patches to the 10.0 branch.  The first one adds
compute support for new hardware, and the last three fix a number of
problems we've been having with statically linked LLVM libraries including
https://bugs.freedesktop.org/show_bug.cgi?id=61364

Thanks,
Tom
