nir/algebraic: Rewrite bit-size inference

Before this commit, there were two copies of the algorithm: one in C,
that we would use to figure out what bit-size to give the replacement
expression, and one in Python, that emulated the C one and tried to
prove that the C algorithm would never fail to correctly assign
bit-sizes. That seemed pretty fragile, and likely to fall over if we
make any changes. Furthermore, the C code was really just recomputing
more-or-less the same thing as the Python code every time. Instead, we
can just store the results of the Python algorithm in the C
datastructure, and consult it to compute the bitsize of each value,
moving the "brains" entirely into Python. Since the Python algorithm no
longer has to match C, it's also a lot easier to change it to something
more closely approximating an actual type-inference algorithm. The
algorithm used is based on Hindley-Milner, although deliberately
weakened a little. It's a few more lines than the old one, judging by
the diffstat, but I think it's easier to verify that it's correct while
being as general as possible.

We could split this up into two changes, first making the C code use the
results of the Python code and then rewriting the Python algorithm, but
since the old algorithm never tracked which variable each equivalence
class, it would mean we'd have to add some non-trivial code which would
then get thrown away. I think it's better to see the final state all at
once, although I could also try splitting it up.

v2:
- Replace instances of "== None" and "!= None" with "is None" and
"is not None".
- Rename first_src to first_unsized_src
- Only merge the destination with the first unsized source, since the
sources have already been merged.
- Add a comment explaining what nir_search_value::bit_size now means.
v3:
- Fix one last instance to use "is not" instead of !=
- Don't try to be so clever when choosing which error message to print
based on whether we're in the search or replace expression.
- Fix trailing whitespace.

different loader. One may support put_image_shm and the other not.

since the same structure was used, the drisw_put_image_shm was used too. Then

radv: reset pending_reset_query when flushing caches

If the driver used a compute shader for resetting a query pool,
it should be completed when caches are flushed.

This might reduce the number of stalls if operations are done
between vkCmdResetQueryPool() and vkCmdBeginQuery()
(or vkCmdWriteTimestamp()).

radv: rework the TC-compat HTILE hardware bug with COND_EXEC

After investigating on this, it appears that COND_WRITE doesn't
work correctly in some situations. I don't know exactly why does
it fail to update DB_Z_INFO.ZRANGE_PRECISION, but as AMDVLK
also uses COND_EXEC I think there is a reason.

Now the driver stores a new metadata value in order to reflect
the last fast depth clear state. If a TC-compat HTILE is fast cleared
with 0.0f, we have to update ZRANGE_PRECISION to 0 in order to
work around that hardware bug.

This fixes rendering issues with The Forest and DXVK and doesn't
seem to introduce any regressions.

mesa/main: correct validation for GL_RGB565

Technically speaking, this validation was incorrect, because GL_RGB565
is only supported in OpenGL ES 1.x if OES_framebuffer_object is
supported. This couldn't lead to any real incorrect behavior, because
all drivers support OES_framebuffer_object. But let's keep the code
self-documenting, by correcting the check as per the spec.
