Because we optimistically skip compiling shaders if we have seen them
before we may need to compile them later at link time if they haven't
yet been use in a specific combination to create a program.
Rather than always recompiling we take advantage of the
gl_compile_status enum introduced in the previous patch to only
compile when we have previously skipped compilation.
This helps with regressions in app start-up times on cold cache
runs, compared with no cache.
Deus Ex: Mankind Divided start-up times:
cache disabled: ~3m15s
cold cache master: ~4m23s
cold cache with this patch: ~3m33s

Previously, when q.subroutine was set to 1, a new subroutine
declaration was added to the AST, while 0 meant a subroutine
definition has been detected by the parser.
Thus, setting the q.subroutine flag in both situations is
obviously wrong because a new type identifier is added instead
of trying to match the declaration. To fix it up, introduce
ast_type_qualifier::is_subroutine_decl() to differentiate
declarations and definitions easily.
This fixes a regression with:

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.

Previously if you used MESA_GL_VERSION_OVERRIDE=3.3COMPAT, Mesa exposed
an OpenGL 3.3 compatibility profile context (with various unimplemented
features and bugs), but still refused to compile shaders with
#version 330 compatibility
This patch simply adds a small bit of plumbing to let that through.
Of course the same caveats apply: compatibility profile is still not
supported (and will not be supported), so there are no guarantees that
anything will work.

This reverts commit 4c86399378.
The commit was erroneous because the ast_layout_expression class was
created to hold a list of values for a layout-qualifier-name which is
allowed to appear in more than one expression in the same
shader/program but not to hold different values.
In other words, the list is used for an after check that all the
declared values for a layout-qualifier-name are consistent.
Therefore, the values stored must match always, not just for
"max_vertices" or any other eventual layout-qualifier-name.

Consider this example:
" #version 150 core
#extension GL_ARB_shading_language_420pack: require
#extension GL_ARB_explicit_attrib_location: require
layout(location=0) out vec4 o;
layout(binding=2) layout(binding=3, std140) uniform U {
vec4 a;
} u[2];"
As there is 2 layout-qualifiers for the uniform U and the binding
layout-qualifier-id is duplicated, the rules set by the
ARB_shading_language_420pack spec state that the rightmost should
prevail.
Our ast_type_qualifier merges with others in a way that if the value
for a layout-qualifier-id is set in both, the object being merged
overwrites the value of the object invoking the merge. Hence, the
merge has to happen from the left layout towards the right one and
this was not happening for interface blocks because we were merging
into the default layout qualifier.
Now, the merge is done from left to right and, as a last step, we
merge into the default layout qualifier if needed, so the values of
the explicit layouts prevail over it.
V2: added a default_layout variable instead of a layout_helper and
make the merge directly over the layout one. Suggested by Timothy.

Generally, we only check for the presence of compute shaders during
parsing when we find any language (like layout qualifiers) that are
specific to compute shaders, however, it is possible to define an
empty compute shader does not use any language specific to compute
shaders at all and we should fail the compilation anyway. dEQP checks
this.
This patch adds a check for compute shader availability after we have
parsed the source code. At this point we know the effective GLSL version
and also extensions enabled in the shader.
Fixes a subcase of the following dEQP tests:
dEQP-GLES31.functional.debug.negative_coverage.callbacks.shader.compile_compute_shader
dEQP-GLES31.functional.debug.negative_coverage.get_error.shader.compile_compute_shader
dEQP-GLES31.functional.debug.negative_coverage.log.shader.compile_compute_shader
The tests still fail because there is one more subcase that fails that needs
