Since the RA has to be done s.t. each one gets its own (adjacent)
register, it would complicate matters if instructions were allowed to be
repeated. This enables copy-propagation use in situations where
previously that might have happened.

We need to keep track if a state change other than frag/vert shader
state will trigger us to need a different shader variant, and if
necessary mark the appropriate shader state as dirty. Otherwise we will
forget to re-emit the shader state.

Keep the existing function as a common helper. But this lets us move an
a2xx specific hack out of common code. And the PIPE_TEX_WRAP_CLAMP
emulation will require an a3xx specific hack. So rather than piling on
hacks, split this out.

4155d1c7 'st/mesa: drop dependence on API profile in st_init_extensions'
broke freedreno because somehow 'PIPE_CAP_MAX_VIEWPORTS' fell through
the cracks. Resulting that we reported zero viewports. So the state
tracker never bothered to give us any valid viewport!

Still some open questions.. and at any rate, no additional piglit passes
due to various wrap modes that we need to emulate in at least some
cases :-(
But it does fix some mystery page-faults.. So add some comments in the
code where there are things that we need to emulate or do more r/e, and
push as-is.

Previously we would get a potentially computed post-swizzle coord based
on the texture target info, which would not include the bias/lod in the
last argument.
The second argument does not have to be adjacent, so adjusting the order
array did not make sense.

(cherry picked from commit 18291ee17a)
4f338c9b introduced logic to trigger a flush rather than overflowing
cmdstream buffer. But the threshold was too low, triggering flushes
where they were not needed. This caused problems with games like
xonotic.
Part of the problem is that we need to mark all state dirty between
cmdstream submit ioctls, because we cannot rely on state being
preserved across ioctls. But even with that, there are still some
problems that are still being debugged. For now:
1) correctly mark all state dirty
2) introduce FD_MESA_DEBUG flush flag to force rendering to be flushed
between each draw, to trigger problems (so that I can debug)
3) use a more reasonable threshold so for normal usecases we don't
trigger the problems
This at least corrects the regression, but there is still more debugging
to do.

Because of render-to-alpha (000x) shenanigans, freedreno needs to do
some special handling when rendering to alpha-only formats. And I
noticed that while we had _is_luminance(), _is_intensity(), etc, an
_is_alpha() helper was missing. So fix that.
