These tests are in core/rotate_e.e with the other rotation tests, and only run on platforms where _EM_LLSIZE == 8.
Also change EM_PSIZE to _EM_PSIZE. I will add _EM_LLSIZE to this test, then all 3 macros will have the leading underscore.
skip the tests which use floating point instructions (as their emulators don't support them).
