radeonsi: Allow dumping LLVM IR before optimization passes
Set R600_DEBUG=preoptir to dump the LLVM IR before optimization passes,
to allow diagnosing problems caused by optimization passes.
Note that in order to compile the resulting IR with llc, you will first
have to run at least the mem2reg pass, e.g.
opt -mem2reg -S < shader.ll | llc -march=amdgcn -mcpu=bonaire
