References CompleteDecl(), and Imported().
Called by StructuralEquivalenceContext.
If a RecordDecl is being compared to another RecordDecl as part of import, completing the other RecordDecl may trigger importation of the first RecordDecl. This happens especially for anonymous structs. If the original of the second RecordDecl can be found, we can complete it without the need for importation, eliminating this loop.

Cope with a name conflict when importing a declaration into the given context.
This routine is invoked whenever there is a name conflict while importing a declaration. The returned name will become the name of the imported declaration. By default, the returned name is the same as the original name, leaving the conflict unresolve such that name lookup for this name is likely to find an ambiguity later.
Subclasses may override this routine to resolve the conflict, e.g., by renaming the declaration being imported.
Name | the name of the declaration being imported, which conflicts with other declarations. |
DC | the declaration context (in the "to" AST context) in which the name is being imported. |
IDNS | the identifier namespace in which the name will be found. |
Decls | the set of declarations with the same name as the declaration being imported. |
NumDecls | the number of conflicting declarations in Decls . |
