Smashing all invalid tests into one function&subtest is imo bad style.
gem_exec_params.c is probably overkill in splitting stuff up, but for this
here at least making some groups of invalid tests as subgroups would be
good imo.

E.g. replacing all your comments with somewhat meaningful subtests names
also helps with making things self-documenting a bit more. Old rule of
thumb that if you write a comment explaining what the code does, it needs
to be refactored to make it obvious what it does.
