This reverts commit aac90ba292.
The commit caused a regression in:
piglit.spec.glsl-1_50.compiler.gs-input-nonarray-named-block.geom
Also the CTS test it was meant to fix seems like it may be bogus.
Cc: "12.0" <mesa-stable@lists.freedesktop.org>
The CTS test:
GL45-CTS.multi_bind.dispatch_bind_image_textures
binds 192 image uniforms, we reject this later,
but not until after we trash the contents of the
struct gl_shader.
Error now reads:
Too many compute shader image uniforms (192 > 16)
instead of
Too many compute shader image uniforms (2745344416 > 16)

This partially fixes CTS test:
GL44-CTS.enhanced_layouts.xfb_get_program_resource_api
The test now fails at a tes evaluation shader with unsized output arrays.
The ARB_enhanced_layouts spec says:
"It is a compile-time error to apply xfb_offset to the declaration of an
unsized array."
So this seems like a bug in the CTS.

The current code disallows unsized arrays except at the end of
an SSBO but it is a bit overzealous in doing so.
struct a {
int b[];
int f[4];
};
is valid as long as b is implicitly sized within the shader,
i.e. it is accessed only by integer indices.
I've submitted some piglit tests to test for this.
This also has no regressions on piglit on my Haswell.
This fixes:
GL45-CTS.shader_storage_buffer_object.basic-syntax

This patch moves a chunk of the linker code down, so
that we don't link the uniform blocks until after we've
merged all the variables. The logic went something like:
Removing the checks for last ssbo member unsized from
the compiler and into the linker, meant doing the check
in the link_uniform_blocks code. However to do that the
array sizing had to happen first, so we knew that the
only unsized arrays were in the last block. But array
sizing required the variable to be merged, otherwise
you'd get two different array sizes in different
version of two variables, and one would get lost
when merged. So the solution was to move array sizing
up, after variable merging, but before uniform block
visiting.

The last version of this broke clipping, and I had to spend
sometime getting this working properly.
I had to introduce a third pass to count the clip/cull totals,
all due to one messy corner case. We have a piglit test
tes-input-gl_ClipDistance.shader_test
that doesn't actually output the clip distances, it just passes
them like a varying from TCS->TES, the older lowering pass worked
but to lower clip/cull we need to know the total number of clip+culls
used to defined the new variable correctly, and to offset culls
properly.
This adds an extra pass that works out the sizes for clip/cull,
then lowers gl_ClipDistance then gl_CullDistance into the new
gl_ClipDistanceMESA.
The pass checks using the fixed array sizes code if they array
has been referenced, or is actually never used, and ignores
it in the latter case.

This fixes a bug that breaks cull distances. The problem
is the max array accessors can't tell the difference between
an never accessed unsized array and an accessed at location 0
unsized array. This leads to converting an undeclared unused
gl_ClipDistance inside or outside gl_PerVertex to a size 1
array. However we need to the number of active clip distances
to work out the starting point for the cull distances, and
this offset by one when it's not being used isn't possible
to distinguish from the case were only the first element is
accessed. I tried to use ->used for this, but that doesn't
work when gl_ClipDistance is part of an interface block.
So this changes things so that max_array_access is an int
and initialised to -1. This also allows unsized arrays to
proceed further than that could before, but we really shouldn't
mind as they will get eliminated if nothing uses them later.
For initialised uniforms we no longer change their array
size at runtime, if these are unused they will get eliminated
eventually.

From the GL 4.5 core spec, section 11.1.1 (Vertex Attributes):
"A program with more than the value of MAX_VERTEX_ATTRIBS
active attribute variables may fail to link, unless
device-dependent optimizations are able to make the program
fit within available hardware resources. For the purposes
of this test, attribute variables of the type dvec3, dvec4,
dmat2x3, dmat2x4, dmat3, dmat3x4, dmat4x3, and dmat4 may
count as consuming twice as many attributes as equivalent
single-precision types. While these types use the same number
of generic attributes as their single-precision equivalents,
implementations are permitted to consume two single-precision
vectors of internal storage for each three- or four-component
double-precision vector."
This commits makes dvec3, dvec4, dmat2x3, dmat2x4, dmat3, dmat3x4,
