  -----------
  Add an attribute registry so plugins can add attributes

When constructing a ParsedAttr the ParsedAttrInfo gets looked up in the
AttrInfoMap, which is auto-generated using tablegen. If that lookup fails then
we look through the ParsedAttrInfos that plugins have added to the registry and
check if any has a spelling that matches.
