    r600g: Use default mul/mad function for tgsi-to-llvm

    Reveiwed-by: Tom Stellard <thomas.stellard at amd.com>

Mesa demos gearbox and fbo_firecube get one of the internal faces blacked out
at certain angles.

R600_LLVM=0 renders properly.

Happens before and after the commits that just went into ~/tstellar/llvm.
