ir_rvalue::constant_expression_value() recursively walks down an IR
tree, attempting to reduce it to a single constant value. This is
useful when you want to know whether a variable has a constant
expression value at all, and if so, what it is.
The constant folding optimization pass attempts to replace rvalues with
their constant expression value from the bottom up. That way, we can
optimize subexpressions, and ideally stop as soon as we find a
non-constant subexpression.
In order to obtain the actual value of an expression, the optimization
pass calls constant_expression_value(). But it should only do so if it
knows the value can be combined into a constant. Otherwise, at each
step of walking back up the tree, it will walk down the tree again, only
to discover what it already knew: it isn't constant.
We properly avoided this call for ir_expression nodes, but not for
ir_swizzle nodes. This patch fixes that, drastically reducing compile
times on certain shaders where tree grafting has given us huge
expression trees. It also fixes SuperTuxKart.
Thanks to Iago and Mike for help in tracking this down.

The FS backend has always used 0, and the VS backend has always used 1.
I think 1 is just working around other problems, and is incorrect.
Samplers are baked in; nothing uses the UNIFORM register we would
create, and we shouldn't upload any constant values for them.
Fixes ES3-CTS.shaders.struct.uniform.sampler_array_vertex.

Samplers take up zero slots and therefore don't exist in the params
array, nor are they included in stage_prog_data->nr_params. There's no
need to store their size in param_size, as it's only used for dealing
with arrays of "real" uniforms (ones uploaded as shader constants).
We run into all kinds of problems trying to refer to the uniform storage
for variables that don't have uniform storage. For one, we may use some
other variable's index, or access out of bounds in arrays. In the FS
backend, our extra 2 * MaxSamplerImageUnits params for texture rectangle
rescaling paper over a lot of problems. In the VS backend, we claim
samplers take up a slot, which also papers over problems.
Instead, just skip allocating storage for variables that don't have any.

We always uploaded them together, mostly out of laziness - both required
an additional vertex element. However, gl_VertexID now also requires an
additional vertex buffer for storing gl_BaseVertex; for non-indirect
draws this also means uploading (a small amount of) data. This is extra
overhead we don't need if the shader only uses gl_InstanceID.
In particular, our clear shaders currently use gl_InstanceID for doing
layered clears, but don't need gl_VertexID.

In the non-indirect draw case, we call intel_upload_data to upload
gl_BaseVertex. It makes brw->draw.draw_params_bo point to the upload
buffer, and increments the upload BO reference count.
So, we need to unreference it when making brw->draw.draw_params_bo point
at something else, or else we'll retain a reference to stale upload
buffers and hold on to them forever.
This also means that the indirect case should increment the reference
count on the indirect draw buffer when making brw->draw.draw_params_bo
point at it. That way, both paths increment the reference count, so
we can safely unreference it every time.

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.

We need the .w component to end up in .x, since the hw appears to fetch
gl_FragColor starting with the .x coordinate regardless of MRT format.
As long as we are doing this, we might as well throw out the remaining

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.

In commit 567e2769b81863b6dffdac3826a6b729ce6ea37c ("ra: make the p, q
test more efficient") I unknowingly introduced a new requirement to the
register allocator API: the user must set the register class of all
nodes before setting up their interferences, because
ra_add_conflict_list() now uses the classes of the two interfering
nodes. i965 already did this, but r300g was setting up register classes
interleaved with setting up the interference graph. This led to us
calculating the wrong q total, and in certain cases
e78a01d5e6f77e075fe667a0f0ccb10d89c0dd58 (" ra: optimistically color
only one node at a time") made it so that this bug caused a segfault. In
particular, the error occurred if the q total was decremented to 1 below
0 for the last node to be pushed onto the stack. Since q_total is an
unsigned integer, it overflowed to 0xffffffff, which is what
lowest_q_total happens to be initialzed to. This means that we would
fail the "new_q_total < lowest_q_total" check on line 476 of
register_allocate.c, and so the node would never be pushed onto the
stack, which led to segfaults in ra_select() when we failed to ever give
it a register.
