Our indirect URB read messages take both a direct and an indirect offset
so when we emit the second message for a 64-bit input load we can just
always incremement the immediate offset, even for the indirect case.

pulls_bary should be set when the shader uses a pixel interpolator
message. So, setting it from the function that emits pixel interpolator
messages makes a lot of sense.

This patch makes emit_general_interpolation take a destination register
as an argument, and write directly to that. This is simpler than the
old approach of ralloc'ing a register, writing to that temporary, and
then making the caller emit per-component MOVs to copy it to the actual
destination.

Likewise, rename the enum type to glsl_interp_mode.
Beyond the GLSL front-end, talking about "interpolation modes" seems
more natural than "interpolation qualifiers" - in the IR, we're removed
from how exactly the source language specifies how to interpolate an
input. Also, SPIR-V calls these "decorations" rather than "qualifiers".

The hardware can only do alphatest when using a blendable format. This
means that the various *16 norm formats didn't work with alphatest. It
appears that Talos Principle uses such formats, as well as alpha tests,
for some internal renders, which made them be incorrect. However this
does not appear to affect the final renders, but in a different game it
easily could.
The approach we take is that when alphatests are enabled and a suitable
format is used (which we anticipate is the vast minority of the time),
we insert code into the shader to perform the comparison and discard.
Once inserted, that code lives in the shader forever, and we re-upload
it each time the function changes with a fixed-up compare. To avoid
re-uploading too often, if we switch back to a blendable format, the
test is (effectively) disabled and the hw alphatest functionality is
used.

In d035d50 this changed to 64b.. which I'm pretty sure was
unintentional. Revert it back to 32b so the entire state struct
is a nice round 64b.
(Note sure that it would actually be measurable, but I did notice
that check_state() was hot in some benchmarks.)

Adds a second optional cleanup callback, called after the fence is
signaled. This is needed if, for example, the queue has the last
reference to the object that embeds the util_queue_fence. In this
case we cannot drop the ref in the main callback, since that would
result in the fence being destroyed before it is signaled.

I recently refactored this to share code between load and atomic

intrin->dest.ssa.num_components. They should be equivalent, but
Jason wanted me to use the latter. I missed applying his review.

The original function was becoming a bit hard to read, with the details
of creating and filling out load/store/atomic atomics all in one
function.
This patch makes helpers for creating each type of intrinsic, and also
combines them with the *_op() helpers, as they're closely coupled and
not too large.

The load/store/atomic cases all duplicated the get_io_offset code, with
a few tiny differences: stores didn't bother checking for per-vertex
inputs, because they can't be stored to, and atomics didn't check at
all, since shared variables aren't per-vertex.
However, it's harmless to check, and allows us to share more code.

Rather than computing the barycentric mode each time we emit a LINTERP,
we can simply compute it once, as soon as we know we're doing non-flat
interpolation.
At that point, emit_linterp() doesn't do much, so fold it into the
call sites and drop it.
