9bfc47358d glsl: avoid stack smashing when there are too many attributes
This fixes a crash in

dEQP-GLES3.functional.transform_feedback.array_element.separate.points.lowp_mat3x2

and likely others. The vertex shader has > 16 input variables (without
explicit locations), which causes us to index outside of the to_assign
array.

c58258558f nir/lower_vec_to_movs: Better report channels handled by insert_mov
This fixes two issues.  First, we had a use-after-free in the case where
the instruction got deleted and we tried to return mov->dest.write_mask.
Second, in the case where we are doing a self-mov of a register, we delete
those channels that are moved to themselves from the write-mask.  This
means that those channels aren't reported as being handled even though they
are.  We now stash off the write-mask before remove unneeded channels so
that they still get reported as handled.

e101a005b1 glsl: always compute proper varying type, irrespective of varying packing
Normally there's a producer and consumer, and the producer var gets
picked. In both the vertex->gs and tes->gs cases, that's the un-arrayed
version.

In the SSO case, however, there is no producer. So we picked the arrayed
GS variable, and as a result, used more slots than we should. More
critically, these slots would also no longer line up with the producer's
calculation. To fix this, we need to fix up the type of the variable
based on stage no matter what.

f9763f24ad glsl: Allow implicit int -> uint conversions for bitwise operators (&, ^, |).
The ARB has decided that implicit conversions should be performed for
bitwise operators in future language revisions.  Implementations of
current language revisions may or may not perform them.

This patch makes Mesa apply implicti conversions even on current
language versions.  Applications appear to expect this behavior,
and there's really no downside to doing so.

dac0229791 glsl: Make bitfield_insert/extract and bfi/bfm non-vectorizable.
Currently, opt_vectorize() tries to combine:

    result.x = bitfieldInsert(src0.x, src1.x, src2.x, src3.x);
    result.y = bitfieldInsert(src0.y, src1.y, src2.y, src3.y);
    result.z = bitfieldInsert(src0.z, src1.z, src2.z, src3.z);
    result.w = bitfieldInsert(src0.w, src1.w, src2.w, src3.w);

into a single ir_quadop_bitfield_insert opcode, which operates on
ivec4s.  However, GLSL IR's opcodes currently require the bits and
offset parameters to be scalar integers.  So, this breaks.

We want to be able to vectorize this eventually, but for now, just
chicken out and make opt_vectorize() bail by marking all the bitfield
insert/extract related opcodes as horizontal.  This is a relatively
uncommon case today, so we'll do the simple fix for stable branches,
and fix it properly on master.

Fixes assertion failures when compiling Shadow of Mordor vertex shaders
on i965 in vec4 mode (where OptimizeForAOS enables opt_vectorize()).

b2352d7585 glsl: Fix varying struct locations when varying packing is disabled.
varying_matches::record tries to compute the number of components in
each varying, which varying_matches::assign_locations uses to assign
locations.  With varying packing, it uses glsl_type::component_slots()
to come up with a reasonable value.

Without varying packing, it fell back to an open-coded computation
that didn't bother to handle structs at all.  I believe we can simply
use 4 * glsl_type::count_attribute_slots(false), which already handles
these cases correctly.

Partially fixes rendering in GFXBench 4.0's tessellation benchmark.
(NVE0 is almost right after this, but i965 is still mostly garbage.)

f7af69c350 glsl: add subroutine index qualifier support
ARB_explicit_uniform_location allows the index for subroutine functions
to be explicitly set in the shader.

This patch reduces the restriction on the index qualifier in
validate_layout_qualifiers() to allow it to be applied to subroutines
and adds the new subroutine qualifier validation to ast_function::hir().

ast_fully_specified_type::has_qualifiers() is updated to allow the
index qualifier on subroutine functions when explicit uniform locations
is available.

A new check is added to ast_type_qualifier::merge_qualifier() to stop
multiple function qualifiers from being defied, before this patch this
would cause a segfault.

Finally a new variable is added to ir_function_signature to store the
index. This value is validated and the non explicit values assigned in
link_assign_subroutine_types().

 Simply appends a qualifier to a list to be merged later by

64710db664 glsl: encapsulate binding validation and setting
This change moves the binding layout handing code into an apply
function to be consistent with other helper functions in the ast
code, and to encapsulate the code so that when we introduce
compile time constants the code will be much cleaner.

One small downside is for unnamed interface blocks we will now
be revalidating the binding for each member its applied to.
However this seems a small sacrifice in order to have code which
is readable.

We also remove the incorrect comment in the named interface code
about propagating bindings to members which seems to have been
copied from the unnamed interface code.

de8f0c9ab9 glsl: add process_qualifier_constant() helper
For now this just validates that a qualifier is inside its
minimum boundary, in a later patch we will expand it to
evaluate compile time constants.

ae6d6941f6 glsl: move builtin_type_macros.h into the correct list
Commit b9b40ef9b7 moved the file, but forgot to update the reference in
the makefile. Thus the out of tree build was busted :\

9108a785a0 glsl: avoid linker and user varying location to overlap
Current behavior on the interface matching:

layout (location = 0) out0; // Assigned to VARYING_SLOT_VAR0 by user
out1; // Assigned to VARYING_SLOT_VAR0 by the linker

New behavior on the interface matching:

layout (location = 0) out0; // Assigned to VARYING_SLOT_VAR0 by user
out1; // Assigned to VARYING_SLOT_VAR1 by the linker

v4:
* Fix variable name in assert

acca6c65d3 nir: add nir_ssa_for_alu_src()
Using something like:

   numer = nir_ssa_for_src(bld, alu->src[0].src,
                           nir_ssa_alu_instr_src_components(alu, 0));

for alu src's with swizzle, like:

   vec1 ssa_10 = intrinsic load_uniform () () (0, 0)
   vec2 ssa_11 = intrinsic load_uniform () () (1, 0)
   vec2 ssa_2 = udiv ssa_10.xx, ssa_11

ends up turning into something like:

   vec1 ssa_10 = intrinsic load_uniform () () (0, 0)
   vec2 ssa_11 = intrinsic load_uniform () () (1, 0)
   vec2 ssa_13 = imov ssa_10
   ...

because nir_ssa_for_src() ignore's the original nir_alu_src's swizzle.
Instead for alu instructions, nir_src_for_alu_src() should be used to
ensure the original alu src's swizzle doesn't get lost in translation:

   vec1 ssa_10 = intrinsic load_uniform () () (0, 0)
   vec2 ssa_11 = intrinsic load_uniform () () (1, 0)
   vec2 ssa_13 = imov ssa_10.xx
   ...

v2: check for abs/neg, and re-use existing nir_alu_src

c73f40c473 nir: fix missing increments of num_inputs/num_outputs
Note: not quite perfect, we should use type_size vfunc (in
compiler_options or nir_shader?) to determine how much we
increment num_inputs/outputs/uniforms.  But we don't have
that yet, so let's at least fix things for the existing
users of these passes.
