219be55807 glsl: add missing error check for half float varying
We should never get here currently as the parser should not even
process float16_t without half float enabled. However it seems
like a good idea to add this for completeness.

81e3b28f78 compiler: Remove C++ static member pointers to builtin types
When we moved the bulk of glsl_type to C, these globals were
kept to avoid changes to compiler/glsl code in the MR.  Now that
landed, change the code to use the actual bultins directly.

b97003e49a glsl: Properly remap GL_* to MESA_PRIM
Instead of blatantly assuming with no assert that they're the same, add
a remap function.  Also, be more careful about which enum we use where.
In the AST, we use GLenum and GL_FOO because we also need GL_ISOLINES.
When we translate to shader info, GS gets translated into mesa_prim
and tessellation gets translated into tess_primitive_mode which has
ISOLINES as a valid primitive value.

3890c60584 compiler/types: Remove unused GLSL_TYPE_FUNCTION and related functions
GLSL doesn't use that type.  SPIR-V used for a while but later started
relying on its own data structures and stopped using it.
See ca62e849d3 ("nir/spirv: Stop using glsl_type for function types")

If we were ever to add this one again, would be better to have a way to
grab a key for lookup that did not require allocations, right now that's
needed to inject return type as the first element in params array.

92c5460253 glsl: mark structs containing images as bindless
Structs are not allowed to contain an image in regular glsl. The only time
they are intended to be allowed to be declared in a struct is when
they are bindless.

Unfortunately the bindless spec does not meantion this behaviour
explicitly so there is no spec quote to reference but you can see in
the original commit to allow them in mesa that spec clarification was
provided 48b7882200

The spec also states that certain uses are implicitly bindless as per
the following spec quote:

   "When used as shader inputs, outputs, uniform block members,
   or temporaries, the value of the sampler is a 64-bit unsigned
   integer handle and never refers to a texture image unit."

Given images are not allowed in regular glsl for the above types
similair to being forbidden in structs, we can also assume
declarations in structs are implicitly bindless.

ddf2778269 glsl: add member's location layout qualifier rules for arrayed in/out blocks
From Section 4.4.1 (Input Layout Qualifiers) of the GLSL 4.50 spec:

     "For some blocks declared as arrays, the location can only be applied
     at the block level: When a block is declared as an array where
     additional locations are needed for each member for each block array
     element, it is a compile-time error to specify locations on the block
     members. That is, when locations would be under specified by applying
     them on block members, they are not allowed on block members. For
     arrayed interfaces (those generally having an extra level of
     arrayness due to interface expansion), the outer array is stripped
     before applying this rule"

From Section 1.2.1 (Changes from Revision 6 of GLSL Version) of the GLSL 4.50 spec:

     "Private Bug 15678: Don’t allow location = on block members where
      the block needs an array of locations"

From Section 4.4.1 (Input Layout Qualifiers) of the GLSL ES 3.20 spec

     "If an input is declared as an array of blocks, excluding per-vertex-arrays
      as required for tessellation, it is an error to declare a member of
      the block with a location qualifier"

From Section 1.1.3 (Changes from GLSL ES 3.2 revision 3) of the GLSL ES 3.20 spec:

     "Arrayed blocks cannot have layout location qualifiers on members"

fa6b22d36a glsl: rework zero initialization

This will allow some flexibility that will be used in the next commit.

84f58a0863 glsl: init gl_FragColor if zero_init=true
This fixes shaders doing "gl_FragColor += ..." and doesn't hurt correct

8059f206da glsl: rename has_implicit_uint_to_int_conversion to *_int_to_uint_*
There is no uint to int implicit conversion in glsl, this is just
a typo in the name of this function. The correct one would be:
has_implicit_int_to_uint_conversion.
