The SIMD16 replicated FB write message only works if we don't need the
color calculator to mask our framebuffer writes. Previously, we bailed
on it if color_mask wasn't <true, true, true, true>. However, this was
needlessly strict for formats with fewer than four components - only the
components that actually exist matter.
WebGL Aquarium attempts to clear a BGRX texture with the ColorMask set
to <true, true, true, false>. This will work perfectly fine with the
replicated data message; we just bailed unnecessarily.
Improves performance of WebGL Aquarium on Iris Pro (at 1920x1080) by
abound 50%, and Bay Trail (at 1366x768) by over 70% (using Chrome 24).
v2: Use _mesa_format_has_color_component() to properly handle ALPHA
formats (and generally be less fragile).
