Fix implementation of C11 6.2.7/4 and C++11 [dcl.array]p3:
When a local extern declaration redeclares some other entity, the type
of that
entity is merged with the prior type if the prior declaration is
visible (in C)
or is declared in the same scope (in C++).
- Make LookupRedeclarationWithLinkage actually work in C++, use it in
the right
set of cases, and make it track whether it found a shadowed
declaration.
- Track whether we found a declaration in the same scope (for C++)
including
across serialization and template instantiation.
