[PATCH] D56868: Add -f[no-]set-visibility-for-decls

Introduce an option to request global visibility settings be applied to declarations without a definition or an explicit visibility, rather than the existing behavior of giving these default visibility. When the visibility of all or most extern definitions are known this allows for the same optimisations `-fvisibility` permits without updating source code to annotate all declarations.
