Here we make the prog_hash_table functionally equivalent to
the one in util by wrapping the remaing functions that differ.
We also move the functions to the header so we can remove the c
file.
This enables us to do a step-by-step replacement of the table.

Unlike the current CSE pass, global value numbering is capable of detecting
common values even if one does not dominate the other. For instance, in
you have
if (...) {
ssa_1 = ssa_0 + 7;
/* use ssa_1 */
} else {
ssa_2 = ssa_0 + 7;
/* use ssa_2 */
}
Global value numbering doesn't care about dominance relationships so it
figures out that ssa_1 and ssa_2 are the same and converts this to
if (...) {
ssa_1 = ssa_0 + 7;
/* use ssa_1 */
} else {
/* use ssa_1 */
}
Obviously, we just broke SSA form which is bad. Global code motion,
however, will repair this for us by turning this into
ssa_1 = ssa_0 + 7;
if (...) {
/* use ssa_1 */
} else {
/* use ssa_1 */
}
This intended to eventually mostly replace CSE. However, conventional CSE
may still be useful because it's less of a scorched-earth approach and
doesn't require GCM. This makes it a bit more appropriate for use as a
clean-up in a late optimization run.

Recent changes to generate ir_expression*.h header files broke Android
builds. This adds the generation rules. This change is complicated due to
creating a circular dependency between libmesa_glsl, libmesa_nir, and
libmesa_compiler. Normally, we add static libraries so that include paths
are added even if there's no linking dependency. That is the case here.
Instead, we explicitly add the include path using $(MESA_GEN_GLSL_H) to
libmesa_compiler. This in turn requires shuffling the order of make
includes. It also uncovered missing dependency tracking of glsl_parser.h.

As of commit d82f8d9772, we actually
parse and attempt to handle the 'patch' qualifier on interface blocks.
This patch fixes explicit locations for variables in such blocks.
Without it, many program interface query dEQP/CTS tests hit this
assertion in ir_set_program_inouts.cpp
if (is_patch_generic) {
assert(idx >= VARYING_SLOT_PATCH0 && idx < VARYING_SLOT_TESS_MAX);
bitfield = BITFIELD64_BIT(idx - VARYING_SLOT_PATCH0);
}
because the location was incorrectly based on VARYING_SLOT_VAR0.
Note that most of the tests affected currently fail before they hit
this, due to confusion about what the program interface query name
of those resources should be.

In 144cbf8 ("nir: Make nir_opt_remove_phis see through moves."), Ken
made nir_opt_remove_phis able to coalesce phi nodes whose sources are
all moves with the same swizzle. However, he didn't add the logic
necessary for handling the fact that the phi may now have multiple
different sources, even though the sources point to the same thing. For
example, if we had something like:
if (...)
a1 = b.yx;
else
a2 = b.yx;
a = phi(a1, a2)
... = a
then we would rewrite it to
if (...)
a1 = b.yx;
else
a2 = b.yx;
... = a1
by picking a random phi source, which in this case is invalid because
the source doesn't dominate the phi. Instead, we need to change it to:
if (...)
a1 = b.yx;
else
a2 = b.yx;
a3 = b.yx;
... = a3;

When NIR was first introduced, Connor added this fake-edge hack to work
around issues related to unreachable blocks. Thanks to GLSL IR's jump
lowering code, the only unreachable code you can have is a block after an
infinite loop. With SPIR-V, we didn't have the jump lowering code so we
could also end up with the "if (...) { break; } else { continue; }" case
which generates an unreachable block after the if. Because of this, most
of NIR had to be fixed up for handling unreachable blocks. The only
remaining case of not handling unreachable blocks was specifically the
block-after-infinite-loop case in dead_cf which was fixed by the previous
commit. We can now delete the fake edge hack.

Varying packing would like to mark certain variables as flat.
This works as long as both sides of the interfaces are changed
accordingly. However, with SSO, we disable varying packing on
the outermost stages. We also disable varying packing for
certain tessellation stages.
With SSO, we operate on the producer and consumer separately.
Checks based on the consumer stage and variable are risky, and
can easily lead to altering one half of the interface between
stages, breaking SSO pipeline IO validation.
Just stop monkeying around with interpolation modes unless
required for varying packing. There's no point. This also
disables it in unsafe SSO cases.

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.

gl_SecondaryFragColorEXT should have the same location as gl_FragColor
for the secondary fragment color to be replicated to all fragment
outputs. The incorrect location of gl_SecondaryFragColorEXT would
cause the linker to mark both FRAG_RESULT_COLOR and FRAG_RESULT_DATA0
as being written to, which isn't allowed by the spec and would
ultimately lead to an assertion failure in
fs_visitor::emit_fb_writes() on my i965-fb-fetch branch.
This should also fix the code below for multiple dual-source-blended
render targets, which no driver currently supports but we have plans
to enable eventually in the i965 driver (the comment saying that no
hardware will ever support it seems rather hilarious).
