<pre>commit c446baa0be1ed2a3bf157519f89a65d348aad17c

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.
