[Mesa-dev] [PATCH 2/6] i965/fs: Allow cmod propagation when src0 is a uniform or shader input

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

No shader-db changes.  This source must have been written by a previous
instruction, so it cannot be a uniform or a shader input.  However, this
change allows the next commit to help about 900 more shaders.
