Determine whether a variable is extern "C" prior to attaching an initializer.
We can't just call isExternC() here, because that will also compute and cache whether the declaration is externally visible, which might change when we attach the initializer.
This can only be used if the declaration is known to not be a redeclaration of an internal linkage declaration.
For instance:
auto x = []{};
Attaching the initializer here makes this declaration not externally visible, because its type has internal linkage.
FIXME: This is a hack.

Determines whether the given declaration is an out-of-scope previous declaration.
This routine should be invoked when name lookup has found a previous declaration (PrevDecl) that is not in the scope where a new declaration by the same name is being introduced. If the new declaration occurs in a local scope, previous declarations with linkage may still be considered previous declarations (C99 6.2.2p4-5, C++ [basic.link]p6).
PrevDecl | the previous declaration found by name lookup |
DC | the context in which the new declaration is being declared. |
