Setting breakpoints using "breakpoint set --selector <SEL>" previously didn't when there was no dSYM file. Also fixed issues in the test suite that arose after fixing the bug. Also fixed the log channels to properly ref count the log streams using weak pointers to the streams. This fixes a test suite problem that would happen when you specified a full path to the compiler with the "--compiler" option. llvm-svn: 171816
