e4da8b9c33 mesa/compiler: rework tear down of builtin/types
The issue we're running into when running CTS is that glsl types are
deleted while builtins depending on them are not.

This happens because on one hand we have glsl types ref counted, but
builtins are not. Instead builtins are destroyed when unloading libGL
or explicitly calling glReleaseShaderCompiler().

This change removes almost entirely any dealing with glsl types
ref/unref by letting the builtins deal with it instead. In turn we
introduce a builtin ref count mechanism. Each GL context takes a
reference on the builtins when compiling a shader for the first time.
It releases the reference when the context is destroyed. It can also
explicitly release those when glReleaseShaderCompiler() is called.

Finally we also take a reference on the glsl types when loading libGL
to avoid recreating glsl types too often.

v2: Ensure we take a reference if we don't have one in link step (Lionel)

624789e370 compiler/glsl: handle case where we have multiple users for types
Both Vulkan and OpenGL might be using glsl_types simultaneously or we
can also have multiple concurrent Vulkan instances using glsl_types.
Patch adds a one time init to track number of users and will release
types only when last user calls _glsl_type_singleton_decref().

This change fixes glsl_type memory leaks we have with anv driver.

6ca652faf3 glsl: be much more aggressive when skipping shader compilation
Currently we only add a cache key for a shader once it is linked.
However games like Team Fortress 2 compile a whole bunch of shaders
which are never actually linked. These compiled shaders can take
up a bunch of memory.

This patch changes things so that we add the key for the shader to
the cache as soon as it is compiled. This means on a warm cache we
can avoid the wasted memory from these shaders. Worst case scenario
is we need to compile the shaders at link time but this can happen
anyway if the shader has been evicted from the cache.

Reduces memory use in Team Fortress 2 from 1.3GB -> 770MB on a
warm cache from start up to the game menu.

V2: only add key to cache when compilation is successful.

c5a4c26450 glsl: Add pragma to disable all warnings
Use #pragma warning(off) and #pragma warning(on) to disable or enable
all warnings.  This is a big hammer.  If we ever need a smaller hammer,
we can enhance this functionality.

There is one lame thing about this.  Because we parse everything, create
an AST, then convert the AST to GLSL IR, we have to treat the #pragma
like a statment.  This means that you can't do something like

'    void
'    #pragma warning(off)
'    __foo
'    #pragma warning(on)
'    (float param0);

Fixing that would, as far as I can tell, require a huge amount of work.

I did try just handling the #pragma during parsing (like we do for
state for the whole shader.

v2: Fix the #pragma lines in the commit message that git-commit ate.

9ce7d79cdc glsl: add a mechanism to allow layout qualifiers on function params
The spec is quite clear this is not allowed:

    From Section 4.4. (Layout Qualifiers) of the GLSL 4.60 spec:

       "Layout qualifiers can appear in several forms of declaration.
       They can appear as part of an interface block definition or
       block member, as shown in the grammar in the previous section.
       They can also appear with just an interface-qualifier to establish
       layouts of other declarations made with that qualifier:

          layout-qualifier interface-qualifier ;

       Or, they can appear with an individual variable declared with
       an interface qualifier:

          layout-qualifier interface-qualifier declaration ;"

    From Section 4.10 (Memory Qualifiers) of the GLSL 4.60 spec:

       "Layout qualifiers cannot be used on formal function parameters,
       and layout qualification is not included in parameter matching."

However on the Nvidia binary driver they actually fail to compile
if image function params don't have a layout qualifier. This results
in applications such as No Mans Sky using layout qualifiers on params.

I've submitted a CTS test to expose this problem in the Nvidia driver
but until that is resolved this patch will help Mesa drivers work
around the issue.

119435c877 mesa: Add GL/GLSL plumbing for INTEL_fragment_shader_ordering
This extension provides new GLSL built-in function
beginFragmentShaderOrderingIntel() that guarantees
(taking wording of GL_INTEL_fragment_shader_ordering
extension) that any memory transactions issued by
shader invocations from previous primitives mapped to
same xy window coordinates (and same sample when
per-sample shading is active), complete and are visible
to the shader invocation that called
beginFragmentShaderOrderingINTEL().

One advantage of INTEL_fragment_shader_ordering over
ARB_fragment_shader_interlock is that it provides a
function that operates as a memory barrie (instead
of a defining a critcial section) that can be called
under arbitary control flow from any function (in
contrast the begin/end of ARB_fragment_shader_interlock
may only be called once, from main(), under no control
flow.

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).

interface blocks are also needed during the linking stage (the last
step), to match re-declared blocks of inter-stage shaders.

This patch adds a new utility function that will factorize current code
that copies functions and variables between two symbol tables, and in
addition will copy explicitly declared gl_PerVertex blocks too.

The function will be used in a subsequent patch.

4d24a7cb97 glsl: fix derived cs variables
There are two issues with the current implementation. First, it relies
on the layout(local_size_*) happening in the same shader as the main
function, and secondly it doesn't work for variable group sizes.

In both cases, the simplest fix is to move the setup of these derived
values to a later time, similar to how the gl_VertexID workarounds are
done. There already exist system values defined for both of the derived
values, so we use them unconditionally, and lower them after linking is
performed.

While we're at it, we move to using gl_LocalGroupSizeARB instead of
gl_WorkGroupSize for variable group sizes.

Also the dead code elimination avoidance can be removed, since there
can be situations where gl_LocalGroupSizeARB is needed but has not been
inserted for the shader with main function. As a result, the lowering
code has to insert its own copies of the system values if needed.

7a7fb90af7 glsl: tidy up IR after loop unrolling
c7affbf687 enabled GLSLOptimizeConservatively on some
drivers. The idea was to speed up compile times by running
the GLSL IR passes only once each time do_common_optimization()
is called. However loop unrolling can create a big mess and
with large loops can actually case compile times to increase
significantly due to a bunch of redundant if statements being
propagated to other IRs.

Here we make sure to clean things up before moving on.

There was no measureable difference in shader-db compile times,
but it makes compile times of some piglit tests go from a couple
of seconds to basically instant.

The shader-db results seemed positive also:

Totals:
SGPRS: 2829456 -> 2828376 (-0.04 %)
VGPRS: 1720793 -> 1721457 (0.04 %)
Spilled SGPRs: 7707 -> 7707 (0.00 %)

Scratch size: 3308 -> 2180 (-34.10 %) dwords per thread
Code Size: 79441464 -> 79214616 (-0.29 %) bytes
LDS: 436 -> 436 (0.00 %) blocks
Max Waves: 558670 -> 558571 (-0.02 %)
Wait states: 0 -> 0 (0.00 %)

a40b3d5a3c glsl: merge loop_controls.cpp with loop_unroll.cpp
Having this separate just makes the code harder to follow, and
requires an extra walk of the IR.
