glsl-bif-tex-lod(advanced.deprec.2d.noProj) 
glsl-bif-tex-lod(advanced.deprec.2d.proj)

Bisect fails due to some mesa commit build failure. The last known bad commit is

Reproduce steps:
----------------
1. start X
2. ./oglconform -z -s -suite all -v 2 -test glsl-bif-tex-lod advanced.deprec.1d.noProj
Comment 1 Ian Romanick 2012-02-10 15:30:32 UTC 
Some analysis has shown that the bad mapping of vertex textures (see bug #45882) is at fault here as well.  I'm closing this bug as a duplicate of that bug.
