On GLES Mesa rejects arrays of arrays as TCS and TES shader inputs and outputs.
This is based on section 4.3 of the GLSL 3.20 ES standard where an error should be
produced for "Per-vertex-arrayed arrays of arrays" and "For non-per-vertex-arrayed
array of arrays", so apparently something like
in vec4 [][N];
is not allowed and on GLES interface blocks have to be used instead. In addition the
code needed some fixups when interface blocks are used.

The shaders are issued backwards starting from the fragment
shader and, therefore, in the first pass when we fill out
the shader keys for the TES no TCS will be present.
So don't bail out in this case and assume there is a VS.
Later, when the VS shader is compiled it will check whether
a TES is present without a TCS and report the error.

Our current CI setup doesn't specify a proper dependency between the
build and test CI stages for merge requests, since the test stage jobs
are triggered on 'merge_requests' whereas the build stage jobs are not.
This leads to both build and test jobs starting in parallel for merge
requests, potentially leading to the tests running with an older docker
image.
This patch triggers the build stage jobs on 'merge_requests' ensuring
correct dependencies.

On GL WR translates to writable, but on GLES we translate this
to writeonly because for most formats one has to specify one or
the other, so if we have an image with the TGSI WR specification,
and read from it, we drop the Writable flag. For the images that
allow RW this is of no consequence, and for the others a write
access will fail instead of the read access, but this doesn't
constitue a regression because we couldn't do both - read and
write - anyway.
