Sometimes users want to execute exactly one checker. This can be done by disabling all checkers and then enabling that one. Some analyzers fail if no checker is enabled. For example, if the user wants to enable one ClangSA checker and disable everything else explicitly, then ClangTidy fails. After this patch an analyzer will not be triggered if all of its checkers are disabled.

Can we tell if the user explicitly enabled an analyzer? If so, we should hard error, shouldn't we?

I can be convinced, but I would feel a hard error a little strong here.
Add --disable-all flag which disables all checkers of all analyzers. It is equilent to using "--disable default".
