Subject: [PATCH] Emulator tests: Correct invalid BEAM code file

In 55eef00e9e0, the literal_case_expression.S file (used by
beam_literals_SUITE) was manually edited to add some more
functions. Unfortunately, the new functions zi1/0 and zi2/0 got the
same entry label (16), but that mistake was not caught at the time,
because the beam_peep pass happened to repair that problem while
renumbering labels.

While at it, also stop the compiler from doing some optimizations.
After all, the purpose of the test suite is to test how the loader and
BEAM machine handles literals.
