This change adds the following options to allow for greater control over the compiler's autolinking directive use:
- '-disable-autolink-library': equivalent to an existing '-disable-autolink-framework', this option takes a library name as input and ensures the compiler does not produce an autolink directive '-l<library-name>'.
- '-disable-autolink-frameworks': a boolean disable flag which turns off insertion of autolinking directives for all imported frameworks (of the type '-framework <framework-name>')
- '-disable-all-autolinking': a boolean disable flag which turns off insertion of *any* autolinking directives.
