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

structures to compile, but those can be obtained directly from
brw_ir_fs.h without including brw_fs.h.  The dependency of
fs_live_variables on fs_visitor is rather accidental and will be
removed in a future commit, a forward declaration is enough for the
moment.

intel/compiler: Nest definition of live variables block_data structures

When this commit was originally written, these two structures had the
exact same name. Subsequently in commit 12a8f2616a2f (intel/compiler:
Fix C++ one definition rule violations) they were renamed.

Original commit message:

> These two structures have exactly the same name which prevents the two
> files from being included at the same time and could cause serious
> trouble in the future if it ever leads to a (silent) violation of the
> C++ one definition rule.

intel/compiler: Reverse inclusion dependency between brw_cfg.h and brw_shader.h

This reflects the natural dependency relationship between brw_cfg.h
and brw_shader.h.  brw_cfg.h only requires the base IR definitions
which are now part of a separate header.

intel/compiler: Move base IR definitions into a separate header file

This pulls out the i965 IR definitions into a separate file and leaves
the top-level backend_shader structure and back-end compiler entry
points in brw_shader.h.  The purpose is to keep things tidy and
prevent a nasty circular dependency between brw_cfg.h and
brw_shader.h.  The logical dependency between these data structures
looks like:

 backend_shader (brw_shader.h) -> cfg_t (brw_cfg.h)
    -> bblock_t (brw_cfg.h) -> backend_instruction (brw_shader.h)

This circular header dependency is currently resolved by using forward
declarations of cfg_t/bblock_t in brw_shader.h and having brw_cfg.h
include brw_shader.h, which seems backwards and won't work at all when
the forward declarations of cfg_t/bblock_t are no longer sufficient in
a future commit.

that is not true anymore, so let's remove that reference and also

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.
