As follow-up to this discussion: https://sourceware.org/pipermail/gdb-patches/2020-August/171385.html ... make runto_main not pass no-message to runto. This means that if we fail to run to main, for some reason, we'll emit a FAIL. This is the behavior we want the majority of (if not all) the time. Without this, we rely on tests logging a failure if runto_main fails, otherwise. They do so in a very inconsisteny mannet, sometimes using "fail", "unsupported" or "untested". The messages also vary widly. This patch removes all these messages as well. Also, remove a few "fail" where we call runto (and not runto_main). by default (without an explicit no-message argument), runto prints a failure already. In two places, gdb.multi/multi-re-run.exp and gdb.python/py-pp-registration.exp, remove "message" passed to runto. This removes a few PASSes that we don't care about (but FAILs will still be printed if we fail to run to where we want to). This aligns their behavior with the rest of the testsuite.
