The main idea behind this is to free some bits in the flags.q
struct because currently all 64-bits are used and we can't
add more layout qualifiers without reaching a static assert.
In order to do that (mainly for ARB_bindless_texture), use an
enumeration for the AMD_conservative_depth layout qualifiers
because it's forbidden to declare more than one depth qualifier
for gl_FragDepth.
Note that ast_type_qualifier::merge_qualifier() will prevent
using duplicate layout qualifiers by returning a compile-time
error.
No piglit regressions found (including compiler tests) with
RX480 on RadeonSI.

OpenGL allows the TCS to be missing and supplies an implicit passthrough
shader, but OpenGL ES does not (see section 7.3 of the ES 3.2 spec,
cited above in the code).
One open question is how to handle this for ARB_ES3_2_compatibility.
This patch raises the link error for all ES shading language programs,
but it might make sense to base it on the API. The approach taken in
this patch is more restrictive, but should still allow any valid ES
programs to work in GL.

From ARB_post_depth_coverage:
"This extension allows the fragment shader to control whether values in
gl_SampleMaskIn[] reflect the coverage after application of the early
depth and stencil tests. This feature can be enabled with the following
layout qualifier in the fragment shader:
layout(post_depth_coverage) in;
Use of this feature implicitly enables early fragment tests."
And a bit later it also adds:
"early_fragment_tests" requests that fragment tests be performed before
fragment shader execution, as described in section 15.2.4 "Early Fragment
Tests" of the OpenGL Specification. If neither this nor post_depth_coverage
are declared, per-fragment tests will be performed after fragment shader
execution."

It will return the current variable ('var') or the earlier declaration ('earlier') in
case of redeclaration of that variable.
In order to distinguish between both, 'is_redeclaration' boolean will indicate in which

The get_variable_being_redeclared() function can free 'var' because
a re-declaration of an unsized array variable can establish the size, so
we set the array type to the 'earlier' declaration and free 'var' as it is
not needed anymore.
However, the same 'var' is referenced later in ast_declarator_list::hir().
This patch fixes it by picking the ir_variable_mode from the proper
ir_variable.
This error was detected by Address Sanitizer.

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.

In order to avoid costly fallback recompiles when cache items are

The hash key for glsl metadata is a hash of the hashes of each GLSL
