The difference between imov and fmov has been a constant source of
confusion in NIR for years. No one really knows why we have two or when
to use one vs. the other. The real reason is that they do different
things in the presence of source and destination modifiers. However,
without modifiers (which many back-ends don't have), they are identical.
Now that we've reworked nir_lower_to_source_mods to leave one abs/neg
instruction in place rather than replacing them with imov or fmov
instructions, we don't need two different instructions at all anymore.

This flag has caused more confusion than good in most cases. You can
validly use imov for floats or fmov for integers because, without source
modifiers, neither modify their input in any way. Using imov for floats
is more reliable so we go that direction.

This greatly simplifies the code to calculate if we should add a
buffer to the resource list. This uses the spec rules and simple
math to decide if we should add the buffer rather than complex
string processing.
This patch refines a patch present in the ARB_gl_spriv merge
request for the NIR linker and applies it to the GLSL IR linker.
This is why we also move the function to the shared linker code,
because we will want to reuse the code for the NIR linker also.

From page 76 (page 80 of the PDF) of the GLSL 4.60 v.5 spec:
" No aliasing in output buffers is allowed: It is a compile-time or
link-time error to specify variables with overlapping transform
feedback offsets."
Currently, this is expected to fail, but it succeeds:
"
...
layout (xfb_offset = 0) out vec2 a;
layout (xfb_offset = 0) out vec4 b;

Commit 624789e370 moved the destruction of types out of atexit() and
made use of a ref count instead. This is useful for avoiding a crash
where drivers such as radeonsi are still compiling in a thread when the app
exits and has not called MakeCurrent to change from the current context.
While the above scenario is technically an app bug we shouldn't crash.
However that change caused another race condition between the shader
compilation tread in radeonsi and context teardown functions.
This patch makes two changes to fix this new problem:
First we explicitly call _mesa_destroy_shader_compiler_types() when destroying
the st context rather than calling it indirectly via _mesa_free_context_data().
We do this as we must call it after st_destroy_context_priv() so that we don't
destory the glsl types before the compilation threads finish.
Next wait for the shader threads to finish in si_destroy_context() this
also means we need to call context destroy before destroying the queues
in si_destroy_screen().

This reverts commit 9e0c744f07, which
regressed dEQP-GLES2.functional.uniform_api.random.3. It turns out
that the newly produced location is meaningless and impossible to
consume by drivers that want to look at gl_uniform_storage, so it's
probably better to leave it unset (0) than a number that looks usable.
Leave a tombstone^Wcomment to discourage the next person from making
the obvious looking fix.
See the next commit for a longer description of the problem.
This breaks tests/spec/glsl-1.10/execution/samplers/uniform-struct

From the OpenGL 4.60.5 spec, section 4.4.1 Input Layout Qualifiers,
Page 67, (Location aliasing):
" Further, when location aliasing, the aliases sharing the location
must have the same underlying numerical type and bit
width (floating-point or integer, 32-bit versus 64-bit, etc.) and
the same auxiliary storage and interpolation qualification."
Additionally, we have improved the linker error descriptions.
Specifically, when taking structs into account we were producing a
linker error because we assumed that all components in each location
were used and that would cause component aliasing. This is not
accurate of the actual problem. Now, the failure specifies that the
underlying numerical type incompatibility is the cause for the
failure.
Fixes the following piglit test:
tests/spec/arb_enhanced_layouts/linker/component-layout/vs-to-fs-width-mismatch-double-float.shader_test
v2:
- Do not assert if we see invalid numerical types. These come
straight from shader code, so we should produce linker errors if
shaders attempt to do location aliasing on variables that are not
numerical such as records.
- While we are at it, improve error reporting for the case of
numerical type mismatch to include the shader stage.
v3:
- Allow location aliasing of images and samplers. If we get these
it means bindless support is active and they should be handled
as 64-bit integers (Ilia)
- Make sure we produce link errors for any non-numerical type
for which we attempt location aliasing, not just structs.
v4:
- Rebased with minor fixes (Andres).
- Added fixing tag to the commit log (Andres).
v5:
- Remove the helper function and check individually for the
underlying numerical type and bit width (Timothy).
- Implicitly, assume that any non-treated type which is checked for
its underlying numerical type is either integer or
float and has a defined bit width (Timothy).
- Implicitly, assume that structs are the only non-treated
non-numerical type (Timothy).
- Improve the linker error descriptions and commit log (Andres).
