test-cases: remove failing test

This causes a stack overflow in a debug build of stage3 unfortunately. I will open an issue to track this test coverage, which we absolutely should get working - users of the compiler should get a compile error, not a segfault if they hit the default branch quota from abusing recursive inline functions. Note that the problem does not occur in a release build of stage3 which has significantly reduced stack usage. On Linux, I tried bumping up the stack size from 32 MiB to 64 MiB and it did not solve the problem. I'm not sure why not. It seems like it should be fine. Note that we also have a problem of running test-cases in multi-threaded mode which is currently the default. Currently Zig threads are spawned with 16 MiB stack space.
