Shaders are usually quite short, and are private to the context. We can
save memory and reduce the work the kernel needs to do at exec time by
packing them together in a stream uploader for long-lived state.
The TFU lets us format raster and SAND images into formats that can be
read by the texture engine, and do mipmap generation.

The HW apparently has some issues (or at least a much more complicated VCM
calculation) with non-combined segments, and the closed source driver also
uses combined I/O. Until I get the last CTS failure resolved (which does
look plausibly like some VPM stomping), let's use combined I/O too.

In the softpin world, surface state base address may be a fixed 64-bit
address (with no associated BO). It makes sense to store this in the
offset field. But it needs to be the full size.
We also update the clear color address to be consistently uint64_t
everywhere so we can continue passing intel_miptree_get_clear_color
a pointer to the blorp_address's offset field without type mismatches.

All conversion opcodes require a destination size but this makes
constructing certain algebraic expressions rather cumbersome. This
commit adds support to nir_search and nir_algebraic for writing
conversion opcodes without a size. These meta-opcodes match any
conversion of that type regardless of destination size and the size gets
inferred from the sizes of the things being matched or from other
opcodes in the expression.

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.

The original code was modifying the global drisw_lf variable, which is bad
when there are multiple contexts in single process, each initialized with
different loader. One may support put_image_shm and the other not.
Since there are currently only two possible combinations, lets create two
global tables, one for each. Lets make them const, since we won't change them
and they can be shared.
This fixes crash in VLC. It used two GL contexts (each in different thread), one
was initialized by its Qt GUI, the other by its video output plugin. The first
one set the put_image_shm=drisw_put_image_shm, the second did not, but
since the same structure was used, the drisw_put_image_shm was used too. Then
it crashed because the second loader did not have putImageShm set.
