    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
