The bug fixed by the previous commit went undetected because extra
stderr messages are not flagged by the CI.  Copy the solution from
fs_visitor::nir_emit_instr and mark the default case unreachable.

An alternate solution is to delete the default case so that the compiler
will issue a warning.  That may require more work since there are other
(impossible) cases that exist.

Some of the lowering passes, nir_lower_locals_to_regs for example, can
cause some previously live code to be dead.  This pass in particular
leaves a bunch of nir_instr_type_deref instructions floating around.
This causes shader-db runs on Gen5 through Haswell to spew tons of
messages like:

    VS instruction not yet implemented by NIR->vec4

UnrealEngine4/EffectsCaveDemo/239.shader_test is one shader that
generates these messages.  Cleaning up the dead code fixes that.

To verify, I did a shader-db before and after.  Even though all the
messages are gone, the results make my brain hurt. :(

On Python 2, the default JSON separators are ', ' for items and ': ' for
dicts.

On Python 3, the default is the same when no indent is specified, but if
one is (and we do specify one) then the default items separator becomes
',' (the dict separator remains unchanged).

This change explicitly specifies the Python 3 default, which helps
ensuring that the output is identical, whether it was generated by

This is a simple, invasive, liberally licensed red-black tree
implementation. It's an invasive data structure similar to the
Linux kernel linked-list where the intention is that you embed a
rb_node struct the data structure you intend to put into the
tree.

The implementation is mostly based on the one in "Introduction to
Algorithms", third edition, by Cormen, Leiserson, Rivest, and
Stein. There were a few other key design points:

 * It's an invasive data structure similar to the [Linux kernel
   linked list].

 * It uses NULL for leaves instead of a sentinel. This means a few
   algorithms differ a small bit from the ones in "Introduction to
   Algorithms".

 * All search operations are inlined so that the compiler can
   optimize away the function pointer call.

This change keeps track of all the memory writes from the aub file and
fetch them on request by the batch decoder. As a result we can get rid

Commit f69bc797 did the following:

-        if format.layout in ('bptc', 'astc'):
+        if format.layout in ('astc'):

The intention was to go from matching either 'bptc' or 'astc' to
matching only 'astc'.

But the new code doesn't respect this intention any more, because in
Python `('astc')` is not a tuple containing a string, it is just the
string. (the parentheses are simply ignored)

That means we now match any substring of 'astc', for example 'a'.

This commit fixes the test to respect the original intention.
