Enable MRT pixel shader rewriting.
Writing to all 8 pixel outputs was causing performance problems on
Intel and AMD. Enabling Geoff's work to rewrite our pixel shaders
solves the regression.
This patch also includes a workaround to the nVidia driver bug
where it would ignore NULL RT values in OMSetRenderTargets, by
compacting the RT list to skip NULL values.
