Kenneth Graunke 86e401b771 i965: Always emit alpha when nr_color_buffers == 0. ... If alpha-testing is enabled, we need to send alpha down the pipeline even if nr_color_buffers == 0. However, tracking whether alpha-testing is enabled in the WM program key is expensive: it causes us to compile multiple specializations of the same shader, using program cache space. This patch removes the check for alpha-testing, and simply emits alpha whenever nr_color_buffers == 0. We believe this will also be necessary for alpha-to-coverage, and it should add minimal overhead to an uncommon case. Saving the recompiles should more than make up the difference.
