Android: glsl: add rules to generate ir_expression*.h header files

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.

nir: fix bug with moves in nir_opt_remove_phis()

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;

nir: Remove fake edges in the CF handling code

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.

nvc0: allow to resize the code segment dynamically

When an application uses a ton of shaders, we need to evict them
when the code segment is full but this is not really a good solution
if monster shaders are used because code eviction will happen a lot.

To avoid this, it seems better to dynamically resize the code
segment area after each eviction. The maximum size is arbitrary
fixed to 8MB which should be enough.

glsl: Only force varyings to be flat when varying packing.

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.

Introduce .editorconfig

A few weeks ago, Jose Fonseca suggested [0] we use .editorconfig files
to try and enforce the formatting of the code, to which Michel Dänzer
suggested [1] we start by importing the existing .dir-locals.el
settings. The first draft was discussed in the RFC [2].

These .editorconfig are a first step, one that has the advantage of
requiring little to no intervention from the devs once the settings
files are in place, but the settings are very limited. This does have
the advantage of applying while the code is being written.
This doesn't replace the need for more comprehensive formatting tools
such as clang-format & clang-tidy, but those reformat the code after
the fact.
