gallium: implement bounds checking for constant buffers
Plumb the constant buffer sizes down into the tgsi interpreter where we can do bounds checking. Optional debug code warns upon out-of-bounds reading. Plus add a few other assertions in the TGSI interpreter.

--- Comment #1 from Marek Olšák maraeo@gmail.com 2010-07-31 22:17:08 PDT --- The thing is the Draw module in Gallium has 3 codepaths: - Slow interpreter - SSE code generation (broken) - LLVM
Guess what, yeah, you use the broken one.
The SSE codepath will most probably be dropped, so I am closing this bug as WONTFIX.
See here: http://lists.freedesktop.org/archives/mesa-dev/2010-July/001658.html
Now you have two options to fix your setup: 1) Compile Mesa with --enable-gallium-llvm to get the LLVM codepath. 2) Set the environment variable GALLIUM_NOSSE=1 to use the slow interpreter.

Fixed by commit aef4500ca4ae9e5bc57560c6f9a32d9ad892975b.
With latest mesa master the same symptoms persist here.

DISREGARD this comment. It is indeed fixed (bug report # mixup)
