The compact flag doesn't make sense on local variables, since the

While normally we give variables whose name field is NULL a temporary
name when called from nir_print_shader(), when we were calling from
nir_print_instr() we never bothered, meaning that we just segfaulted
when trying to print out instructions with such a variable. Since
nir_print_instr() is meant to be called while debugging, we don't need
to bother too much about giving a consistent name, but we don't want to
crash in the middle of debugging.

_mesa_glsl_has_builtin_function is used to determine whether any variant
of a builtin are available, for the purpose of enforcing the GLSL ES
3.00+ rule that overloads or overrides of builtins are disallowed.
However the builtin_builder contains information on all builtins,
irrespective of parse state, or versions, or extension enablement. As a
result we would say that a builtin existed even if it was not actually
available.
To resolve this, first check if at least one signature is available for
a builtin before returning true.

Now that we have a pointer wrapper class, we can create offsets for UBOs

Everyone now calls it with stop_at_matrix = false. Since we're now

Instead of handling all of the complexity at the end, we choose to
decorate types a bit more cleverly. When we have a row-major matrix
type, we give it the stride of a single vector and give it's array
element type (which represents a column) the actual matrix stride.
Previously, we were using stop_at_matrix and handling everything from
matrix on down as special cases but now we walk the access chain all the
way to the end and then load. Even though this looks like it may lead
to a significant functional change, it doesn't. The reason why we
needed to do stop_at_matrix before was to handle row-major properly
since the offsets and strides would be all out-of-order. Now that row
major matrix types have the small stride on the matrix and the large
stride on the vector, offsetting to a single column of a row-major
matrix works fine. The load/store code simply picks up on the fact that
the stride isn't the type size and does multiple loads. The generated
code from these methods should be the same.

The vtn_pointer structure provides a bit better abstraction than passing
access chains around directly. For one thing, if the pointer just
points to a variable, we don't need the access chain at all. Also,
pointers know what their dereferenced type is so we can avoid passing
the type in a bunch of places. Finally, pointers can, in theory, be
extended to the case where you don't actually know what variable is
being referenced.

Doom shipped with a broken version of GLSLang which handles samplers as

it creates a temporary local sampler variable and copies the sampler
into it. While Dave has had a hack patch out for a while that gets it
working, we've never landed it because we've been hoping that a game
update would come out with fixed shaders. Unfortunately, no game update
appears on to be on the horizon and I've found this issue in yet another
application so I think we're stuck working around it. Hopefully, we can
delete this code one day.
