Print which warning-flag controls an emitted warning.wip/D1934
Summary:
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.
Fixes T10752.
