Weave shader dumps

It looks like LLVM miscompiles the weave fragment shader due to the changes to
descriptor loading. See the attached file. With these changes, LLVM generates
some really odd looking and inefficient code in this case, and the two sample
instructions are somehow folded together, which cannot possibly work.

Someone proficient in LLVM can probably figure out what is going wrong.
