lowering. This catch all isn't very useful anymore - we can just add it

This simplifies things. Every caller of brw_nir_lower_io() immediately
calls brw_postprocess_nir(). The only real change this will have is
that we get an extra brw_nir_optimize() call when compiling compute
shaders, but that seems fine.

We've now hit literally every case other than geometry shaders (and
compute shaders, but those are a no-op). So, let's just move geometry
shaders over too and be done with it.
The only advantage to doing this at link time was to save the expense
of running the pass on recompiles. But we're already running a lot of
passes, and the extra code complexity isn't worth it.

The Vulkan driver wants to be able to delete fragment outputs that are

Without this, on SIMD 16 the send instruction destination will appear
to write more than one destination register, causing the simulator to
report an error.
Of course, the send instruction can actually write more than one
destination register regardless of the type set for the destination,
so this is a bit strange.

Previously loops like
do {
// ...
} while (false);
that did not have any other loop-branch instructions would not be
unrolled. This is commonly used to wrap multiline preprocessor macros.
This produces IR like
(loop (
...
break
))
Since limiting_terminator was NULL, the loop unroller would
throw up its hands and say, "I don't know how many iterations. How
can I unroll this?"
We can detect this another way. If there is no limiting_terminator
and the only loop-branch is a break as the last IR, there's only one
iteration.
On my very old checkout of shader-db, this removes a loop from Orbital
Explorer, but it does not otherwise affect the shader. The loop removed
is the one the compiler inserts surrounding the switch statement.
This change does prevent some seriously bad code generation in some
patches to meta shaders that I recently sent out for review.

The change "mesa/readpix: Don't clip in _mesa_readpixels()" caused a
few piglit regressions. The failing tests use glReadPixels to read
from the front color buffer. The problem is we were trying to read
from a non-existant front color buffer. The front color buffer is
created on demand in st/mesa. Since the missing buffer bounds were
effectively 0 x 0 the glReadPixels was totally clipped and returned
early.
The fix involves creating the real front color buffer when we're about
to try reading from it.

The current code in r600_translate_colorswap uses the swizzle information
to determine which colorswap to use.
This works for BE & LE when the nr_channels is <4, but when nr_channels==4
(e.g. PIPE_FORMAT_A8R8G8B8_UNORM), this method can not be used for both BE
and LE, because the swizzle info is the same for both of them.
As a result, r600g doesn't support 24bit color formats, only 16bit, which
forces the user to choose 16bit color in X server.
This patch fixes this bug by separating the checks for LE and BE and
adapting the swizzle conditions in the BE part of the checks.
