AST: Mangle fields in anonymous structs/unions
The Itanium mangler couldn't cope with mangling an IndirectFieldDecl.
Instead, mangle the field the IndirectFieldDecl refers to.
Further, give IndirectFieldDecl no linkage just like FieldDecl.
N.B. Decl.cpp:getLVForNamespaceScopeDecl tried to calculate linkage for
data members of anonymous structs/unions. However, this seems
impossible so turn it into an assertion.
