4f42450b86 glsl: allow any l-value of an input variable as interpolant in interpolateAt*
The intended rule has been clarified in GLSL 4.60, Section 8.13.2
(Interpolation Functions):

   "For all of the interpolation functions, interpolant must be an l-value
    from an in declaration; this can include a variable, a block or
    structure member, an array element, or some combination of these.
    Component selection operators (e.g., .xy) may be used when specifying
    interpolant."

For members of interface blocks, var->data.must_be_shader_input must be
determined on-the-fly after lowering interface blocks, since we don't want
to disable varying packing for an entire block just because one input in it
is used in interpolateAt*.

v2: keep setting must_be_shader_input in ast_function (Ian)
v3: follow the relaxed rule of GLSL 4.60
v4: only apply the relaxed rules to desktop GL
    (the ES WG decided that the relaxed rules may apply in a future version
     but not retroactively; see also
     dEQP-GLES31.functional.shaders.multisample_interpolation.interpolate_at_centroid.negative.*)

49d9286a3f glsl: stop copying struct and interface member names
We are currently copying the name for each member dereference
but we can just share a single instance of the string provided
by the type.

This change also stops us recalculating the field index
repeatedly.

57dc6d80a0 glsl: Drop resize-to-MaxPatchVertices hack.
TCS and TES inputs without an array size are implicitly sized to
gl_MaxPatchVertices.  But TCS outputs are apparently not:

   "If no size is specified, it will be taken from the output patch size
    (gl_VerticesOut) declared in the shader."

Fixes dEQP-GLES31.functional.program_interface_query.program_output.

173558445d glsl: Size TCS->TES unsized arrays to gl_MaxPatchVertices for queries.
SSO validation and other program interface queries want to see that
unsized (non-patch) TCS output/TES input arrays are implicitly sized
to gl_MaxPatchVertices.

By the time we create the program resource lists, we've sized the arrays
to their actual size.  (We try to create TCS output arrays to match the
output patch size right away, and at this point, we should have shrunk
TES input arrays.)  One option would be to keep them sized to
gl_MaxPatchVertices, and defer shrinking them.  But that's a big change,
and I don't think it's a good idea.

Instead, this patch introduces a new ir_variable flag which indicates
the variable is implicitly to gl_MaxPatchVertices.  Then, the linker
munges the types when creating the resource list, ignoring the size
in the IR's types.  Basically, lie about it for resource queries.
It's ugly, but I think it ought to work.

We probably could use var->data.implicit_sized_array for this, but
I opted for a separate bit to try and avoid convoluting the existing
SSBO handling.  They're similar in concept, but share none of the
same code...

Fixes:
ES31-CTS.core.tessellation_shader.single.xfb_captures_data_from_correct_stage
and the ES32-CTS and ESEXT-CTS variants.

v2: Add a comment (requested by Timothy, written by me).

1fb8c6df88 glsl/mesa: split gl_shader in two
There are two distinctly different uses of this struct. The first
is to store GL shader objects. The second is to store information
about a shader stage thats been linked.

The two uses actually share few fields and there is clearly confusion
about their use. For example the linked shaders map one to one with
a program so can simply be destroyed along with the program. However
previously we were calling reference counting on the linked shaders.

We were also creating linked shaders with a name even though it
is always 0 and called the driver version of the _mesa_new_shader()
function unnecessarily for GL shader objects.

8765a9e0fe glsl: generate named interface block names correctly
Firstly this updates the named interface lowering pass to store the
interface without the arrays removed.

Note we need to remove the arrays in the interface/varying matching
code to not regress things but in future this should be fixed
futher as it would seem we currently successfully match interface
blocks with differnt array sizes.

Since we now know if the interface was an array we can reduce the
IR flags from_named_ifc_block_array and from_named_ifc_block_nonarray
to just from_named_ifc_block.

Next rather than having a different code path for named interface
blocks in program_resource_visitor we just make use of the one used
by UBOs this allows us to now handle arrays of arrays correctly.

Finally we add a new param to the recursion function
named_ifc_member this is because we only want to process a single
member at a time. Note that this is also the glsl_struct_field
from the original ifc type before lowering rather than the type
from the lowered variable. This fixes a bug in Mesa where we would
generate the names like WithInstArray[0].g[0][0] when it should be
WithInstArray[0].g[0] for the following interface.

   out WithInstArray {
      float g[3];
   } instArray[2];
