    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.
