[Mesa-dev] [PATCH 3/3] nine: Drop use of TGSI_OPCODE_CND.

[Eric Anholt]

From: Jose Fonseca <jfonseca at vmware.com>

This was the only state tracker emitting it, and hardware was just having
to lower it anyway (or failing to lower it at all).

v2: Extracted from a larger patch by Jose (which also dropped DP2A), fixed
    to actually not reference TGSI_OPCODE_CND.  Change by anholt.
