Before, we were always treating it as an output which bogus. The only
stage in which this it can be an output is the geometry stage. In all
other stages, it's an input which, in the back-end, we actually want to be
a system value.

No change in behavior. ralloc_size is equivalent to rzalloc_size.
That will change though.
Calls not switched to rzalloc_size:
- ralloc_vasprintf
- glsl_type::name allocation (it's filled with snprintf)
- C++ classes where valgrind didn't show uninitialized values
I switched most of non-glsl stuff to rzalloc without checking whether
it's really needed.

When restoring something from shader cache we won't have and don't
want to create a nir_shader this change detaches the two.
There are other advantages such as being able to reuse the
shader info populated by GLSL IR.

Previously, we dind't apply variable decorations to the members of a split
structure variable. This doesn't quite work, unfortunately, because things
such as the "flat" qualifier may get applied to an entire structure instead
of propagated to the members. This fixes 9 of the new CTS tests in the
dEQP-VK.glsl.linkage.varying.struct.* group.

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".

I have no idea why we were multiplying by 4 before. The offsets we get
from SPIR-V are in bytes and so is nir->num_uniforms so there's no need to
do any adjustment whatsoever.

SPIR-V treats it as an input but NIR wants the system value. This
shouldn't have been too much of a surprise given that we have to do the
same conversion in the GLSL IR to NIR pass.

glslang frequently throw bogus decorations into shaders. While we are free
to assert-fail, it's a bit nicer to the application to just warn.

SPIR-V specifies that a bunch of stuff gets applied to types. This means
taht a local variable could get, for instance, an array stride. Just
because it's pointless doesn't mean you'll never see it.
From time to time we have had cases where glslang has added a decoration we
don't handle and it has caused problems. This audit ensures that, for
every decoration, we either handle it or hit an unreachable() with an
accurate description of why we don't have to.
This isn't allowed by Vulkan, but might be useful someday for
SPIR-V in OpenGL (if that ever becomes a thing). It's easy enough
to hook up, and as precedent, we already do so for OriginLowerLeft.

We want to use interface_type, not vtn_var->type. They're normally
equivalent, but for geometry/tessellation per-vertex interface arrays,
we need to unwrap a level.
Otherwise, we tried to iterate a structure members but instead used
an array length. If the array length was longer than the number of
fields in the structure, we'd crash.
Fixes the CreatePipelineGeometryInputBlockPositive layer validation
test.
v2: Just use glsl_without_array() on the vtn_var type
(requested by Jason Ekstrand).

While it does rely on NIR, it's not really part of the NIR core. At the
moment, it still builds as part of libnir but that can be changed later if
desired.
