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.

commit c446baa0be1ed2a3bf157519f89a65d348aad17c
Author: Michel Danzer <michel.daenzer@amd.com>
Date: Fri Mar 22 14:09:10 2013 +0000
R600: Use legacy (0 * anything = 0) MUL instructions for pow intrinsics
Fixes wrong lighting in some corner cases with r600g and radeonsi, e.g.
manifested by failure of two piglit/glean tests and intermittent black
patches in many apps.
Tested on SI and RS880.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=58150 [r600g]
NOTE: This is a candidate for the Mesa stable branch.
