radeon/llvm: Run LLVM's instruction combining pass
This should improve code quality in general and will help with some
future changes to how we emit kill instructions.
shader-db shows a few regressions, but these don't seem to be the result
of deficiencies in instcombine. They're mostly caused by the scheduler
making different decisions than before.
Unigine Valley quits saying -
Unhandled loop condition!
UNREACHABLE executed at SIAnnotateControlFlow.cpp:267!
Only tried my normal settings on valley which are
quality ultra + 8x AA</pre>
