[Mesa-dev] [PATCH 3/3] i965/fs: Don't consider the stencil output to be a color output.

[Francisco Jerez]

This would cause gl_FragStencilRef to be counted as a color output
incorrectly during the precompile phase, which leads to unnecessary
recompilation on master and could trigger an assertion failure in
fs_visitor::emit_fb_writes() on my i965-fb-fetch branch.
