[PATCH] D80977: Diagnose cases where the name of a class member is used within a class definition before the member name is declared.

[Richard Smith - zygoloid via Phabricator via cfe-commits]

rsmith created this revision.
rsmith added a reviewer: rnk.
Herald added a project: clang.

This is ill-formed per [basic.scope.class]p2.

This is done by tracking all unqualified lookups performed within the
scope of a class definition that find nothing within the class, and
checking for conflicting declarations later introduced into the class.
