LOG: [NFC] Add a comment to member-function-pointer-calls.cpp

Looking at this test I did not see why MinGW was using a different command
line until I looked at the git history. Add a comment explaining what this
RUN line is actually testing. Also add two more RUN lines to show that
indirectly passed member pointers don't inhibit the optimization.
