bz#344560 - Also fixes memcheck/tests/badpoll test on OS X - Problem occurs because the guest stack seen in a system call pre or post function happens to not have a correct topmost stack frame, as Darwin system call stubs do not start with the usual function prolog. - New regression test case added. - Thanks to Greg Banks for research, patch and test case. Before: == 587 tests, 240 stderr failures, 22 stdout failures, 0 stderrB failures, 0 stdoutB failures, 31 post failures == After: == 588 tests, 239 stderr failures, 22 stdout failures, 0 stderrB failures, 0 stdoutB failures, 31 post failures == git-svn-id: svn://svn.valgrind.org/valgrind/trunk@14985
