New tests to check that, with separable program objects, interface
matching by name or location are still checked at link time between
the inner interfaces existing inside the program.
From the ARB_separate_shader_objects spec v.25:
" With separable program objects, interfaces between shader stages
may involve the outputs from one program object and the inputs
from a second program object. For such interfaces, it is not
possible to detect mismatches at link time, because the programs
are linked separately. When each such program is linked, all
inputs or outputs interfacing with another program stage are
treated as active. The linker will generate an executable that
assumes the presence of a compatible program on the other side of
the interface. If a mismatch between programs occurs, no GL error
will be generated, but some or all of the inputs on the interface
will be undefined."
