9f3d5e99ea compiler: Use util/bitset.h for system_values_read
It is currently a bitset on top of a uint64_t but there are already
more than 64 values.  Change to use BITSET to cover all the
SYSTEM_VALUE_MAX bits.

25efd787cf compiler: Move double_inputs to gl_program::DualSlotInputs
Previously, we had two field in shader_info: double_inputs_read and
double_inputs.  Presumably, the one was for all double inputs that are
read and the other is all that exist.  However, because nir_gather_info
regenerates these two values, there is a possibility, if a variable gets
deleted, that the value of double_inputs could change over time.  This
is a problem because double_inputs is used to remap the input locations
to a two-slot-per-dvec3/4 scheme for i965.  If that mapping were to
change between glsl_to_nir and back-end state setup, we would fall over
when trying to map the NIR outputs back onto the GL location space.

This commit changes the way slot re-mapping works.  Instead of the
double_inputs field in shader_info, it adds a DualSlotInputs bitfield to
gl_program.  By having it in gl_program, we more easily guarantee that
NIR passes won't touch it after it's been set.  It also makes more sense
to put it in a GL data structure since it's really a mapping from GL
slots to back-end and/or NIR slots and not really a NIR shader thing.

f63e05ae9e compiler: tidy up double_inputs_read uses
First we move double_inputs_read into a vs struct in the union,
double_inputs_read is only used for vs inputs so this will
save space and also allows us to add a new double_inputs field.

We add the new field because c2acf97fcc changed the behaviour
of double_inputs_read, and while it's no longer used to track
actual reads in i965 we do still want to track this for gallium
drivers.

957ec00243 Revert recent GLSL slot counting fiasco.
I apparently broke mark_whole_variable in ir_set_program_inouts.
It was passing a type that wasn't var->type, so the wrapper didn't
work out.  It's all broken, revert it and start over.

Fixes all kinds of things on other drivers.

the variable is actually a varying.

5c580e64cc glsl: Mark whole variable used for ClipDistance and TessLevel*.
There's no point in trying to mark partial array access for
gl_ClipDistance, gl_TessLevelOuter, or gl_TessLevelInner - they're
special built-in variables that control fixed function hardware,
and will likely be used in an all-or-nothing fashion.

Since these arrays only occupy 1-2 varying slots, we have to avoid
our normal processing which increments the slot value by the array
index.

(I wrote this code before i965 switched from ir_set_program_inouts
to nir_shader_gather_info.  It's not used by anyone today, and I'm
not sure how valuable it is...the alternative to GLSL IR lowering
is NIR compact arrays, at which point you should use nir_gather_info.)

fd04d048ae glsl: Fix gl_program::OutputsWritten computation for dual-source blending.
In the fragment shader OutputsWritten is a bitset of FRAG_RESULT_*
enumerants, which represent the location of each color output written
by the shader.  The secondary and primary color outputs of a given
render target using dual-source blending have the same location, so
the 'idx' computation below will give the wrong bit as result if the
'var->data.index' term is non-zero -- E.g. if the shader writes the
primary and secondary colors of the FRAG_RESULT_COLOR output,
ir_set_program_inouts will think that the shader writes both
FRAG_RESULT_COLOR and FRAG_RESULT_SAMPLE_MASK, which is just bogus.

That would cause the brw_wm_prog_key::nr_color_regions computation
done in the i965 driver during fragment shader precompilation to be
wrong, which currently leads to unnecessary recompilation of shaders
that use dual-source blending, and triggers an assertion failure in
fs_visitor::emit_fb_writes() on my i965-fb-fetch branch.

4a49851da1 glsl: Delete bogus ir_set_program_inouts assert.
This assertion is bogus.  Varying structs, and arrays of structs, are
allowed by GLSL, and we can see them here.  While we currently don't
have any partial-variable support for those, simply returning false
and marking the entire thing as used is certainly legitimate.

I believe this is often swept under the rug by varying packing,
but that's disabled in certain tessellation situations.

Hit by 20 dEQP-GLES31.functional.tessellation.user_defined_io.* tests.

ac1181ffbe compiler: Rename INTERP_QUALIFIER_* to INTERP_MODE_*.
Likewise, rename the enum type to glsl_interp_mode.

Beyond the GLSL front-end, talking about "interpolation modes" seems
more natural than "interpolation qualifiers" - in the IR, we're removed
from how exactly the source language specifies how to interpolate an
input.  Also, SPIR-V calls these "decorations" rather than "qualifiers".
