[Mesa-dev] [PATCH] llvmpipe: align the array used for subdivived vertices

[Zack Rusin]

When subdiving a triangle we're using a temporary array to store
the new coordinates for the subdivided triangles. Unfortunately
the array used for that was not aligned properly causing
random crashes in the llvm jit code which was trying to load
vectors from it.
