When a TCS is present, the TES input gl_PatchVerticesIn is actually a
constant - it's simply the # of output vertices specified by the TCS
layout qualifiers. So, we can replace the system value with a constant,
which may allow further optimization, and will likely be more efficient.
If the TCS is absent, we can't do this optimization.

This is more optimal as it means we no longer have to upload the same set
of ABO surfaces to all stages in the program.
This also fixes a bug where since commit c0cd5b var->data.binding was
being used as a replacement for atomic buffer index, but they don't have
to be the same value they just happened to end up the same when binding is 0.

This corresponds to instructions used on vc4 for its blending inside of
shaders. I've seen these opcodes on other architectures before, but I
think it's the first time these are needed in Mesa.

Location has never been able to be a negative value because it has
always been validated in the parser.
Also the linker doesn't check for negatives like the comment claims.

process_parameters() will now be called earlier because we need
actual_parameters processed earlier so we can use it with
match_subroutine_by_name() to get the subroutine variable, we need
to do this inside the recursive function generate_array_index() because
we can't create the ir_dereference_array() until we have gotten to the
outermost array.
For the remainder of the array dimensions the type doesn't matter so we
can just use the existing _mesa_ast_array_index_to_hir() function to
process the ast.

This also removes the validation from the parser as it is not required

Move glsl_types into NIR, now that the dependency on glsl_symbol_table

Before d31f98a272 and 56e2bdbca3 we had a sigle index space for UBOs
and SSBOs, so NumBufferInterfaceBlocks would contain the combined number of
blocks, not just one kind. This means that for shader programs using both
UBOs and SSBOs, we were setting num_ssbos and num_ubos to a larger number than
we should. Since the above commits we have separate index spaces for each
so we can just get the right numbers.

This marks all counters in an AoA as active.
For AoA all but the innermost array are treated as separate
counters/uniforms. The Nvidia binary also goes further and
finds inactive counters in the AoA, in future we should do
this too, however this gets things working for the time being.
This change also removes the use of UniformHash for atomic counters,
this avoids having to generate name strings used as hash keys.
