[r600g] Is LLVM-compiler (--enable-r600-llvm-compiler) usable, now?

Hello Michel,

subject say it all ;-)

Second, we are now nearly on par with 3.16 on RV730 (AGP) with all your latest work, but I think about what we could get if we find the right commit between 3.16 (.4 here) and 3.17-rc1 (the transition from 3.16 to 3.17-next).

I do not have 3.16.x around (it is not any longer in the openSUSE kernel current tree) but with latest 3.16.4 I was faster then with all 3.17.x and 3.18/3.19-next kernels.

bisect do not work right or I couldn't revert the 'right' commit. WC helped on RV730 (AGP) with some apps, here:

mesa-demos e.g. vsraytrace fsraytrace objview

Any ideas?
