heaven + llvm on rv790 rendering errors.

rv790 with git mesa and svn llvm, testing unigine heaven 3.0 like -

MESA_EXTENSION_OVERRIDE=-GL_ARB_shader_bit_encoding 
force_glsl_extensions_warn=true  ./heaven

I haven't tested this for a while - it was OK sometime ago with FDO llvm but
now I am getting some rendering errors (scree shot attached) with current mesa
git and llvm svn.

I tried finding a working commit going back with mesa, but I get to a point
where llvm renders nothing at all with anything using current llvm svn.

R600_LLVM=0 has no problems.
