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

glsl/linker: dvec3/dvec4 consume twice input vertex attributes

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."
