Guard band clipping speeds up rasterization for primitives that are
partially off-screen. This change in particular results in small
framerate improvements in a wide range of games.

and clamp it right before emitting. This is a prerequisite for computing
the guard band.

Just for consistency. This should have no effect, because OpenGL textures
always go to VRAM.

The closed driver does this, but it looks at base_level and last_level
and uses a conditional assignment, which LLVM can't generate on SGPRs.
That led me to invent this solution that abuses the image descriptor.

Just for consistency. This is actually not a problem, because both addrlib
and radeon check and fix this.

This is a remnant of the times when the DDX was allocating depth-stencil
buffers for windows. Now, st/dri allocates them and doesn't share them.

For atomic operations we really need to avoid executing unnecessary shaders, so for some
tests that just draw a single point we only want one vertex to get processed not 4,
this fixes a number of the atomic counters tests.

out the pragma [that inspired the original commit].
Building mesa requires MSVC2013 or later, thus we no longer need this.

This lets us write the Z directly from the FTOI for computed Z, and may
let us coalesce color writes in the future.
No change in my shader-db, but clearly drops an instruction in piglit's
early-z test.
