INTERP is defined (by me) to have to have a INPUT source. However the
state tracker does not always obey this. This happens due to varying
packing logic introducing additional mov's which can't always be undone.
Instead of just giving up, we instead try harder to find the original
input. This won't always be possible, for example with indirect
accesses. There's not much we can (easily) do about that though.
This fixes the remaining interpolateAt* failures in dEQP:
dEQP-GLES31.functional.shaders.multisample_interpolation.interpolate_at*
some of which were asserting due to INTERP_* being passed a non-input.

These tests were causing a const vbo to be set up, and were small enough
draws that the logic was trying to go via the push path (which emits
data directly into the cmd stream rather than uploading a user vbo).

This was handled in handleTEX(), however the way the logic works, those
extra arguments aren't added on by then, so it did nothing. Instead we
must duplicate that bit here. GK110 appears to complain about
MISALIGNED_GPR, however it's reasonable to believe that GK104 has the
same requirements.

Cull distances are just a special case of clip distances as far as the

The helper was initially created to allow us to set reasonable defaults as
we mutated the brw_blorp_prog_data structure in preparation for NIR. Now
that everything is going through brw_blorp_compile_nir_shader() which fully
fills out the brw_blorp_prog_data structure, we don't need the helper.

NIR gets kind of awkward when you have a 3-component vector with two floats
and one int. This led to us accidentally going through float for the
sample index. It doesn't hurt anything but it also isn't needed.

Intel hardware does a form of multisample compression that involves an
auxilary surface called the MCS. When an MCS is in use, you have to first
sample from the MCS with a special opcode and then pass the result of that
operation into the next sample instrucion. Normally, we just do this
ourselves in the back-end, but we want to expose that functionality to NIR
so that we can use MCS values directly in NIR-based blorp.

There's no reason for having a macro *and* a python generator. We can

The hardware packets organize kernel pointers and GRF start by slots that
don't map directly to dispatch width. This means that all of the state
setup code has to re-arrange the data from prog_data into these slots.
This logic has been duplicated 4 times in the GL driver and one more time
in the Vulkan driver. Let's just put it all in brw_fs.cpp.

Now that we have a persample_shading bit in prog_data we can reduce the
amount the state setup code needs to be looking at the GL state. In
particular, it no longer pulls anything directly out of the
gl_fragment_program and no longer depends on NEW_FRAGMENT_PROGRAM.

This commit reworks and simplifies the way we handle persample shading in
the shader key and prog_data. The previous approach had three different
key bits that had slightly different and hard-to-decern meanings while the
new bits are far more clear. This commit changes it to two easily
understood bits that communicate everything we need:
1) key->persample_interp: means that the user has requested persample
interpolation through the API. This is equivalent to having
SAMPLE_SHADING enabled and having MIN_SAMPLE_SHADING_VALUE set high
enough that you actually get multiple per-sample invocations.
2) key->multisample_fbo: means that the shader will be running on an
actual multi-sampled framebuffer.
This commit also adds a new "persample_dispatch" bit to prog_data which
indicates that the shader should be run in persample mode. This way the
state setup code doesn't have to look at the fragment program or GL state
and can just pull that data out of the prog_data.
In theory, this shuffle could mean more recompiles. However, in practice,
we were shoving enough state into the key before that we were probably
hitting a recompile on every per-sample shader anyway.

Commit 5310bca024 added a new "double df"
field to the brw_reg struct, adding an extra 4 bytes of data that isn't
usually initialized (or may contain irrelevant garbage if the struct is
mutated). This means that it's no longer safe to memcmp().
Instead, add a brw_regs_equal() function which ignores the extra df bits
unless they matter. To keep the implementation cheap, we wrap the first
set of fields in a union/struct so that we can use a single DWord
comparison.
