Most older drivers seem to just ignore the Dimension setting, so virtually
no changes should be needed.

Commit e1af20f18a86f52a9640faf2d4ff8a71b0a4fa9b changed the shader_info
from being embedded into being just a pointer. The idea was that
sharing the shader_info between NIR and GLSL would be easier if it were
a pointer pointing to the same shader_info struct. This, however, has
caused a few problems:
1) There are many things which generate NIR without GLSL. This means
we have to support both NIR shaders which come from GLSL and ones
that don't and need to have an info elsewhere.
2) The solution to (1) raises all sorts of ownership issues which have
to be resolved with ralloc_parent checks.
3) Ever since 00620782c92100d77c660f9783504c6d80fa1d58, we've been
using nir_gather_info to fill out the final shader_info. Thanks to
cloning and the above ownership issues, the nir_shader::info may not
point back to the gl_shader anymore and so we have to do a copy of
the shader_info from NIR back to GLSL anyway.
All of these issues go away if we just embed the shader_info in the
nir_shader. There's a little downside of having to copy it back after
calling nir_gather_info but, as explained above, we have to do that
anyway.

The NIR story on conversion opcodes is a mess. We've had way too many
of them, naming is inconsistent, and which ones have explicit sizes was
sort-of random. This commit re-organizes things and makes them all
consistent:
- All non-bool conversion opcodes now have the explicit size in the
destination and are named <src_type>2<dst_type><size>.
- Integer <-> integer conversion opcodes now only come in i2i and u2u
forms (i2u and u2i have been removed) since the only difference
between the different integer conversions is whether or not they
sign-extend when up-converting.
- Boolean conversion opcodes all have the explicit size on the bool and
are named <src_type>2<dst_type>.
Making things consistent also allows nir_type_conversion_op to be moved
to nir_opcodes.c and auto-generated using mako. This will make adding
int8, int16, and float16 versions much easier when the time comes.

Likewise, rename the enum type to glsl_interp_mode.
Beyond the GLSL front-end, talking about "interpolation modes" seems
more natural than "interpolation qualifiers" - in the IR, we're removed
from how exactly the source language specifies how to interpolate an
input. Also, SPIR-V calls these "decorations" rather than "qualifiers".

This commit adds the capability to NIR to support separate textures and
samplers. As it currently stands, glsl_to_nir only sets the texture deref
and leaves the sampler deref alone as it did before and nir_lower_samplers
assumes this. Backends can still assume that they are combined and only
look at only at the texture index. Or, if they wish, they can assume that
they are separate because nir_lower_samplers, tgsi_to_nir, and prog_to_nir
all set both texture and sampler index whenever a sampler is required (the
two indices are the same in this case).

We're about to separate the two concepts. When we do, the sampler will
become optional. Doing a rename first makes the separation a bit more
safe because drivers that depend on GLSL or TGSI behaviour will be fine to
just use the texture index all the time.

A hugely common case when using nir_builder is to have a shader with a
single function called main. This adds a helper that gives you just that.
This commit also makes us use it in the NIR control-flow unit tests as well

When Connor originally drafted NIR, he copied the same function+overload
system that GLSL IR had with a few names changed. However, this
double-indirection is not really needed and has only served to confuse
people. Instead, let's just have functions which may not have unique names
and may or may not have an implementation. If someone wants to do overload
resolving, they can hav a hash table based function+overload system in the
overload resolving pass. There's no good reason to keep it in core NIR.

Tessellation control shaders need to be careful when writing outputs.
Because multiple threads can concurrently write the same output
variables, we need to only write the exact components we were told.
Traditionally, for sub-vector writes, we've read the whole vector,
updated the temporary, and written the whole vector back. This breaks
down with concurrent access.
This patch prepares the way for a solution by adding a writemask field
to store_var intrinsics, as well as the other store intrinsics. It then
updates all produces to emit a writemask of "all channels enabled". It
updates nir_lower_io to copy the writemask to output store intrinsics.
Finally, it updates nir_lower_vars_to_ssa to handle partial writemasks
by doing a read-modify-write cycle (which is safe, because local
variables are specific to a single thread).
This should have no functional change, since no one actually emits
partial writemasks yet.
v2: Make nir_validate momentarily assert that writemasks cover the
complete value - we shouldn't have partial writemasks yet
(requested by Jason Ekstrand).
v3: Fix accidental SSBO change that arose from merge conflicts.
v4: Don't try to handle writemasks in ir3_compiler_nir - my code
for indirects was likely wrong, and TTN doesn't generate partial
writemasks today anyway. Change them to asserts as requested by
Rob Clark.

There is some special-casing needed in a competent back-end. However, they
can do their special-casing easily enough based on whether or not the
offset is a constant. In the mean time, having the *_indirect variants
adds special cases a number of places where they don't need to be and, in
general, only complicates things. To complicate matters, NIR had no way to
convdert an indirect load/store to a direct one in the case that the
indirect was a constant so we would still not really get what the back-ends
wanted. The best solution seems to be to get rid of the *_indirect
variants entirely.
This commit is a bunch of different changes squashed together:
- nir: Get rid of *_indirect variants of input/output load/store intrinsics
- nir/glsl: Stop handling UBO/SSBO load/stores differently depending on indirect
- nir/lower_io: Get rid of load/store_foo_indirect
- i965/fs: Get rid of load/store_foo_indirect

- vc4: Fix load_user_clip_plane crash
- vc4: add missing src for store outputs
- vc4: Fix state uniforms
- nir/lower_clip: Update to the new load/store intrinsics
