[Mesa-dev] [PATCH v2] gallivm, llvmpipe: Handle MSAA textures in emit_fetch_texels.

[Darius Goad]

This support is preliminary due to the fact that MSAA is not
actually implemented. More complete support would most likely
involve a rework of the Mesa architecture to support it.

However, this patch does fix the piglit test:
