intel/compiler: Define more detailed analysis dependency classes
I've deliberately separated this from the general analysis pass
infrastructure in order to discuss it independently. The dependency
classes defined here refer to state changes of several objects of the
program IR, and are fully orthogonal and expected to change less often
than the set of analysis passes present in the compiler back-end.
The objective is to avoid unnecessary coupling between optimization
and analysis passes in the back-end. By doing things in this way the
set of flags to be passed to invalidate_analysis() can be determined
from knowledge of a single optimization pass and a small set of well
specified dependency classes alone -- IOW there is no need to audit
all analysis passes to find out which ones might be affected by
certain kind of program transformation performed by an optimization
pass, as well as the converse, there is no need to audit all
optimization passes when writing a new analysis pass to find out which
ones can potentially invalidate the result of the analysis.
The set of dependency classes defined here is rather conservative and
mainly based on the requirements of the few analysis passes already
part of the back-end. I've also used them without difficulty with a
few additional analysis passes I've written but haven't yet sent for
review.

nir/linker: remove reference to just SPIR-V linking
Several files had a initial comment about the purpose of such files,
including a reference that the NIR linker was implemented with just
ARB_gl_spirv in mind.
Since the nice job Timothy is doing to use the NIR linker on GLSL,
that is not true anymore, so let's remove that reference and also
tweak some other comments.

iris: Don't skip fast depth clears if the color changed
We depend on BLORP to convert the clear color and write it into the
clear color buffer for us. However, we weren't bothering to call blorp
in the case where the state is ISL_AUX_STATE_CLEAR. This leads to the
clear color not getting properly updated if we have back-to-back clears
with different clear colors. Technically, we could go out of our way to
set the clear color directly from iris in this case but this is a case
we're unlikely to see in the wild so let's not bother. This matches
what we already do for color surfaces.
