This commit fixes two issues: First, we were returning false regardless
of whether or not the function made progress. Second, we were calling
nir_metadata_preserve far more often than needed; we only need to call
it once per impl.

Having 4 variables all called "gl_in_TexCoord0@n" isn't very informative,
much better to see:
decl_var shader_in INTERP_MODE_NONE float gl_in_TexCoord0 (VARYING_SLOT_VAR0.x, 1, 0)
decl_var shader_in INTERP_MODE_NONE float gl_in_TexCoord0@0 (VARYING_SLOT_VAR0.y, 1, 0)
decl_var shader_in INTERP_MODE_NONE float gl_in_TexCoord0@1 (VARYING_SLOT_VAR0.z, 1, 0)

This is intended to be called before nir_lower_io() so that we

I've been doing this inside of vc4, but vc5 wants it as well and it may be
useful for other drivers (Intel has a related path for pre-gen6 with MRT,
and freedreno had a TGSI path for it at one point).
This required defining a common enum for the standard comparison
functions, but other lowering passes are likely to also want that enum.
v2: Add to meson.build as well.

In truth gtest is an external dependency that upstream expects you to

This allows building and installing the Intel "anv" Vulkan driver using
meson and ninja, the driver has been tested against the CTS and has
seems to pass the same series of tests (they both segfault when the CTS
tries to run wayland wsi tests).
There are still a mess of TODO, XXX, and FIXME comments in here. Those
are mostly for meson bugs I'm trying to fix, or for additional things to
implement for other drivers/features.
I have configured all intermediate libraries and optional tools to not
build by default, meaning they will only be built if they're pulled in
as a dependency of a target that will actually be installed) this allows
us to avoid massive if chains, while ensuring that only the bits that
need to be built are.
v2: - enable anv, x11, and wayland by default
- add configure option to disable valgrind
v3: - fix typo in meson_options (Nicholas)
v4: - Remove dead code (Eric)
- Remove change to generator that was from v0 (Eric)

- Fix typos (Eric)

Clang warns:
warning: absolute value function 'fabsf' given an argument of type
'const float64_t' (aka 'const double') but has parameter of type 'float'
which may cause truncation of value [-Wabsolute-value]
float64_t dst = bit_size == 64 ? fabs(src0) : fabsf(src0);
The type of the ternary expression will be the common type of fabs() and
fabsf(): double. So fabsf(src0) will be implicitly converted to double.
We may as well just convert src0 to double before a call to fabs() and
remove the needless complexity, à la
float64_t dst = fabs(src0);

Note that while ballotARB(true) will return zeros in the high 32-bits on
systems where gl_SubGroupSizeARB <= 32, the gl_SubGroup??MaskARB
variables do not consider whether channels are enabled. See issue (1) of
ARB_shader_ballot.

If the source is an indirect register, there is ralloc'd data. Copying
with a direct assignment will copy the pointer, but the data will still
belong to the old instruction's memory context. Since we're lowering
and throwing away instructions, that could free the data by mistake.
Instead, use nir_src_copy, which properly handles this.
This is admittedly not a common case, so I think the bug is real,
but unlikely to be hit.

While normally we give variables whose name field is NULL a temporary
name when called from nir_print_shader(), when we were calling from
nir_print_instr() we never bothered, meaning that we just segfaulted
when trying to print out instructions with such a variable. Since
nir_print_instr() is meant to be called while debugging, we don't need
to bother too much about giving a consistent name, but we don't want to
crash in the middle of debugging.
