DXIL metadata strings and function names have a limited size. Truncate
the name when they don't fit. This is a quick&dirty workaround since it
doesn't address the problem for all kind of strings, and doesn't ensure
there's no collision in the function names after the truncation. That's
not an issue right now because I don't think we have implementations
keeping more than one function (the entrypoint), but it might be a
problem at some point.

Right now we had two methods that tries to optimize the nir shader,
nir_optimize and st_nir_opts. The latter is being used when we are
linking, but again, it has basically the same purpose that
nir_optimize.
So this commit adds more lowerings to nir_optimize_nir, add some extra
comments on the method, and replaces st_nir_opts with nir_optimize.
Ideally we would like to just use the already existing
v3d_optimize_nir that we have at the backend But:
* Using it leads to some regressions on Vulkan CTS tests, due some
lowerings that are already there.
* We would need to move to the backend some additional
lowerings/optimizations that are used on the Vulkan
frontend. That would require to check that we are not getting any
regression or performance drop on OpenGL
So for now we are keeping a Vulkan specific nir_optimize method.
Additionally this fixes the following test:
dEQP-VK.graphicsfuzz.cov-loop-condition-clamp-vec-of-ones

That is what most others Vulkan drivers do (radv, anv, turnip at
least).
The origin of this change cames from a CTS test where the loop
unrolling converted a ubo index defined inside a loop from constant to
non constant. That is not desiderable on any driver, but a problem on
v3dv, as v3dv doesn't support that case.
Although we initially tried to fix it on the loop unroll, we discarded
that approach, and focused on the existing nir lowerings/optimizations
as this was not happening with other drivers.
We noted that in other drivers this case of a ubo index going from
const to non-const were also happening with nir_lower_explicit_io, but
in that case it was able to be converted back to a const on following
lowerings. The only difference with other drivers is that we were
calling it before the first nir optimization loop.
So this change helps with fixing the following CTS test (for that we
also need to run additional lowerings, which we do in a later patch):
dEQP-VK.graphicsfuzz.cov-loop-condition-clamp-vec-of-ones

Since we only consume barriers at the beginning of a new job, if
a command buffer ends with a barrier we will not handle it. Fix
this by emitting a noop job in that case to consume it. Ideally,
we could do better and check the pending barrier state to fine
tune the noop job so we don't wait on all queues, but for now
this fixes flakyness with some CTS pipeline barrier tests that
started to show up after we optimized binning sync barriers. It
is likely that the additional sync we had before that change was
enough to prevent the problem from showing up.

We are already doing the 0*anything = 0 by default and we are also
using the DX versions of math ops like RCP. It looks like R300 and
R400 can't do IEEE math anyway (but its hard to tell without docs).
For R500 we can do IEEE math, but testing showed that some apps
are dependent on the DX behavior, so considering we only advertise
GLSL 1.20 where this is left ot the driver, just keep the curent
status and expose PIPE_CAP_LEGACY_MATH_RULES so that nine can stop
emiting math workarounds.

Rather than generating shaders to clear depth and stencil attachments, run the
rasterizer without a shader and configure the depth/stencil hardware to do the
clear. These settings are known to be efficient on Valhall, presumably the
depth/stencil pipeline on Bifrost is similar enough that it is also the
efficient way there. It's certainly much simpler.

On Bifrost and newer, blend descriptors are decoupled from render target. That
means we can always use a clear shader reading from blend_descriptor_0 and
specify the desired render target in the sole blend descriptor we pass.
Likewise on Bifrost and newer we don't need blend descriptors when we don't
blend, which is the case for the Z/S clears.
This reduces the number of shaders compiled on startup from 468 to 426.
