glCompileShader can use two different sources, so we need 2 different SHA1s
there. Successful compilation sets compiled_source_sha1.

strlen and others will be added in the following commits. The idea is to

The GLSL spec says it's an error if a shader statically writes to these
2 variables.
Until this commit, Mesa refused to link a shader if it had an unused
function writing to one of these variables while another (used) function
wrote to the other.
This commit adds an option to perform dead function elimination after
the intra-stage linking step but before performing these checks.

This is separate from images and samplers. It's a texture (not a
storage image) without a sampler. We also add C-visible helpers to
convert between sampler and image types.

With the `gtest` protocol meson will add some extra arguments to the
test to generate better junit results, which may be useful. This
protocol is only available in meson 0.55.0+, so keep using the default
`exitcode` protocol for meson older than that.

We don't use it for bindless images because the uniforms in that case
just contain a bindless handle and aren't an actual image. Bound
images, on the other hand, go in the nir_var_mem_image class.

This is basically the same workaround as in 9b577f2a88 (driconf, glsl: Add a
vs_position_always_invariant option) commit but for tesselation evaluation
shaders. Some applications do not mark outputs as precise in tesselation
evaluation shaders which can lead to different results in case some
optimizations were applied.

It only makes sense to call this pass for fragment shaders, and the
first thing the pass does is read a FS-specific field out of a union,
so it isn't safe to call it for other shader stages.
We could make it early return, but instead we just assert, so that
drivers know to only call it when appropriate.
(A previous version of this patch, which early returned instead of
asserting, was Reviewed-by: Emma Anholt <emma@anholt.net> as well.)

Clang analyzer thinks struct_base_offset can be used uninitialized
because it doesn't know that glsl_type_is_struct_or_ifc returns
the same value for the same type.
Refactor the code to make it clear what is going on. As a side effect
this should be faster because glsl_get_length and
glsl_type_is_struct_or_ifc will be called only once (they are not
inline functions).

When operators other than eq and ne are involved we can't really
move operands around and negate them because such transformation
may change the value of the whole expression.
Some examples:
For unsigned var:
0 >= 1u + var would eventually become 0xffffffff >= var,
which would always evaluate to true, when original expression
was true only for var == 0xffffffff.
For signed var:
0 >= 1 + var would become -1 >= var, which would evaluate to
false for var == 2147483647, when original expression evaluated
to true (because signed overflow is defined to wrap around in
glsl, 1 + 2147483647 == -2147483648, so 0 >= -2147483648).
