If an unsized declared array is not the last in an SSBO
and an implicit size can not be defined on linking time,
the linker should raise an error instead of reaching
an assertion on GL.
This reverts part of commit 3da08e1664
getting back to the behavior of commit 5b2675093e
The original patch was correct for GLES that should produce
a compile-time error but the linker error is still necessary
in desktop GL.
Fixes the following piglit tests:
tests/spec/arb_shader_storage_buffer_object/non_integral_size_array_member.shader_test
tests/spec/arb_shader_storage_buffer_object/unsized_array_member.shader_test

This one only keeps allocated memory in the list, and list nodes
in the descriptor sets. Thsi doesn't need messing around with
max_sets, and we get automatic merging of free regions.

We only use the freed ones after all free space has been used. If
the app only allocates small descriptor sets, we might go over
max_sets before the memory is full.

data source elements aligned to 64-bit but only with doubles as
destination type.

The optimization in unpack_64 is clearly subsumed with the opt_algebraic
optimizations in the previous commit. The pack optimization may not be
quite handled by opt_algebraic but opt_algebraic should get the really
bad cases. Also, it's been broken since it was merged and we've never
noticed so it must not be doing anything.

NIR is a typeless IR and the two opcodes, when considered bitwise, do
exactly the same thing. There's no reason to have two versions.

We can only do the optimization if the source *is* SSA.

In order to avoid costly fallback recompiles when cache items are
created with an old version of Mesa or for a different gpu on the
same system we want to create directories that look like this:
./{TIMESTAMP}_{LLVM_TIMESTAMP}/{GPU_ID}
Note: The disk cache util will take a single timestamp string, it is
up to the backend to concatenate the llvm string with the mesa string
if applicable.

Here we skip the recreation of uniform storage if we are relinking
after a cache miss. This is improtant because uniform values may
have already been set by the application and we don't want to reset
them.

This will allow us to skip certain things when falling back to
a full recompile on a cache miss such as avoiding reinitialising
uniforms.
In this change we use it to avoid reading the program metadata
from the cache and skipping linking during a fallback.

These may be lowered constant arrays or uniform values that we set before linking
so we need to cache the actual uniform values.

For now this disables the shader cache when transform feedback is
enabled via the GL API as we don't currently allow for it when

V2: don't store pointers use an enum instead to flag what should be
restored. Also do the work in a helper that we will later use for

The three additional tables are AttributeBindings, FragDataBindings,
and FragDataIndexBindings.
The first table (AttributeBindings) was identified as missing by
trying to test the shader cache with a program that called
glGetAttribLocation.
Many thanks to Tapani Pälli <tapani.palli@intel.com>, as it was review
of related work that he had done previously that pointed me to the
necessity to also save and restore FragDataBindings and
FragDataIndexBindings.

The scenario is:
glShaderSource
glCompileShader <-- deferred due to cache hit of shader
glShaderSource <-- with new source code
glAttachShader
glLinkProgram <-- no cache hit for program
At this point we need to compile the original source when we
fallback.

The hash key for glsl metadata is a hash of the hashes of each GLSL
source string.
This commit uses the put_key/get_key support in the cache put the SHA-1
hash of the source string for each successfully compiled shader into the
cache. This allows for early, optimistic returns from glCompileShader
(if the identical source string had been successfully compiled in the past),
in the hope that the final, linked shader will be found in the cache.
This is based on the intial patch by Carl.

This uses disk_cache.c to write out a serialization of various
state that's required in order to successfully load and use a
binary written out by a drivers backend, this state is referred to as
"metadata" throughout the implementation.
This initial version is intended to work with all stages beside
compute.
This patch is based on the initial work done by Carl.
V2: extend the file's doxygen comment to cover some of the
design decisions.
V3:
- skip cache for fixed function shaders
- add int64 support
- fix glsl IR program parameter caching/restore and cache the
parameter values which are used by gallium backends.
- use new link status enum
V4:
- add compute program support
