[Mesa-dev] Radeonsi OpenGL 4.0 compat profile

[Timothy Arceri]

This series is intended to be applied on top of my previous compat 
series [1]. Note I'm going to drop the last two patches from that 
series, patch 10 was sent by mistake and I've submitted a spec bug 
in regards to patch 11.

I originally planned not to send this series until 
ARB_vertex_attrib_64bit was done and we could enable 4.4. However
it seems that extension will require a fair number of changes.
