LLVM assembly of shader

The attached shader (LLVM assembly, dumped with R600_DEBUG=ps) fails to compile with latest LLVM trunk. AFAIR it worked at some point with some combination of Mesa and LLVM, but I couldn't reproduce this.

Compile with
> llc -march=amdgcn -mcpu=SI -mattr=+vgpr-spilling -verify-machineinstrs < bug.ll

to reproduce. It looks like it is spilling related.

I can't reproduce this anymore. Closing.
