Print which warning-flag controls an emitted warning
Both gcc and clang tell which warning flag a reported warning can be controlled with, this patch makes ghc do the same. More generally, this allows for annotated compiler output, where an optional annotation is displayed in brackets after the severity. This also adds a new flag `-f(no-)show-warning-groups` to control whether to show which warning-group (such as `-Wall` or `-Wcompat`) a warning belongs to. This flag is on by default. This implements #10752 Reviewed By: quchen, bgamari, hvr Differential Revision: https://phabricator.haskell.org/D1943
