f0cdc39b13 meson: remove dependency antipattern
`dep_valgrind != []` now (0.45) produces a warning that is quite explicit:
  WARNING: Trying to compare values of different types (DependencyHolder, list) using !=.
  The result of this is undefined and will become a hard error in a future Meson release.

`dep_valgrind = []` used to be the recommended way to deal with
non-existant dependency, but these don't work with `.found()`, so now
the recommended way is to declare a impossible dependency, which
null_dep does for us in Mesa.

In short, we don't need and shouldn't check for `!= []` anywhere anymore.

901db25d5b glsl: change ast_type_qualifier bitset size to work around GCC 5.4 bug
Change the size of the bitset from 128 bits to 96.  This works around an
apparent GCC 5.4 bug in which bad SSE code is generated, leading to a
crash in ast_type_qualifier::validate_in_qualifier() (ast_type.cpp:654).

This can be repro'd with the Piglit test tests/spec/glsl-1.50/execution/
varying-struct-basic-gs-fs.shader_test

1ff1dc1c63 glsl/glcpp: Handle hex constants with 0X prefix
GLSL 4.6 spec describes hex constant as:

hexadecimal-constant:
    0x hexadecimal-digit
    0X hexadecimal-digit
    hexadecimal-constant hexadecimal-digit

Right now if you have a shader with the following structure:

    #if 0X1 // or any hex number with the 0X prefix
    // some code
    #endif

the code between #if and #endif gets removed because the checking is performed
only for "0x" prefix which results in strtoll being called with the base 8 and
after encountering the 'X' char the strtoll returns 0. Letting strtoll detect
the base makes this limitation go away and also makes code easier to read.

From the strtoll Linux man page:

"If base is zero or 16, the string may then include a "0x" prefix, and the
number will be read in base 16; otherwise, a zero base is taken as 10 (decimal)
unless the next character is '0', in which case it is taken as 8 (octal)."

This matches the behaviour in the GLSL spec.

This patch also adds a test for uppercase hex prefix.

3b52d29227 glsl/tests: reimplement warnings-test in python
This reimplements the test in python with a shell script wrapper that
allows autotools to continue to run the test without realizing that
anything has changed.

Using python has two advantages, first it's portable so this test can be
run on windows as well as Linux since it just requires python, no more
diff, pwd or sh. It's also no longer tied to autotools implementation
details, like the environment variables $srcdir and $abs_builddir,
though the autotools shell wrapper still uses those, which makes it
possible to run the test in meson.

Just checking for 2 jumps is not enough to be sure we can do a

2 loop terminators.

Without this we were attempting to unroll a loop where the second
jump was nested inside multiple ifs which loop analysis is unable
to detect as a terminator. We ended up splicing out the first
terminator but failed to actually unroll the loop, this resulted
in the creation of a possible infinite loop.

537bb1da98 glsl: Specify framebuffer fetch coherency mode in lower_blend_equation_advanced().
This requires passing an extra argument to the lowering pass because
the KHR_blend_equation_advanced specification doesn't seem to define
any mechanism for the implementation to determine at compile-time
whether coherent blending can ever be used (not even an "#extension
KHR_blend_equation_advanced_coherent" directive seems to be required
in the shader source AFAICT).

In the long run we'll probably want to do state-dependent recompiles
based on the value of ctx->Color.BlendCoherent, but right now there
would be no benefit from that because the only driver that supports
coherent framebuffer fetch is i965 on SKL+ hardware, which are unable
to support the non-coherent path for the moment because of texture
layout issues, so framebuffer fetch coherency is always enabled for
them.

ef9e3f63ca glsl: Add support for the framebuffer fetch layout(noncoherent) qualifier.
This allows the application to request framebuffer fetch coherency
with per-fragment output granularity.  Coherent framebuffer fetch
outputs (which is the default if no qualifier is present for
compatibility with older versions of the EXT_shader_framebuffer_fetch
extension) will have ir_variable_data::memory_coherent set to true.

0aeec504b4 glsl: Allow layout token for EXT_shader_framebuffer_fetch_non_coherent.
EXT_shader_framebuffer_fetch_non_coherent requires layout qualifiers
even on GL(ES) 2.

1bc01db95f glsl: Initialize ir_variable_data::fb_fetch_output earlier for GL(ES) 2.
At the same point where it is initialized on GL(ES) 3.0+ so we can
implement some common layout qualifier handling in a future commit.
Until now the fb_fetch_output flag would be inherited from the
original implicit gl_LastFragData declaration at a later point in the
AST to GLSL IR translation.

ba79a90fb5 glsl: Switch ast_type_qualifier to a 128-bit bitset.
This should end the drought of bits in the ast_type_qualifier object.
The bitset_t type works pretty much as a drop-in replacement for the
current uint64_t bitset.

The only catch is that the bitset_t type as defined in the previous
commit doesn't have a trivial constructor (because it has a
user-defined constructor), so it cannot be used as union member
without providing a user-defined constructor for the union (which
causes it in turn to be non-trivially constructible).  This annoyance
could be easily addressed in C++11 by declaring the default
constructor of bitset_t to be the implicitly defined one -- IMO one
more reason to drop support for GCC 4.2-4.3.

The other minor change was required because glsl_parser_extras.cpp was
hard-coding the type of bitset temporaries as uint64_t, which (unlike
would have been the case if the uint64_t had been replaced with
e.g. an __int128) would otherwise have caused a build failure, because
the boolean conversion operator of bitset_t is marked explicit (if
C++11 is available), so the bitset won't be silently truncated down to
1 bit in order to use it to initialize the uint64_t temporaries
(yikes).

183ce5e629 glsl: Parse 'layout' as a token with advanced blending or bindless
Both KHR_blend_equation_advanced and ARB_bindless_texture provide
layout qualifiers, and are exposed in compatibility contexts.  We
need to parse the layout qualifier as a token in order for those
to work, but forgot to extend this check.

ARB_shader_image_load_store would need a similar treatment, but we
don't expose that in legacy OpenGL contexts.
