glsl: Add an option to clamp block indices when lowering UBO/SSBOs

This prevents array overflow when the block is actually an array of UBOs or
SSBOs.  On some hardware such as i965, such overflows can cause GPU hangs.

The previous code got the BO the first time we encountered it.  However,
this can potentially lead to problems if the BO is used for multiple arrays

glsl: rewrite clip/cull distance lowering pass

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.

glsl: make max array trackers ints and use -1 as base. (v2)

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.
