Subject: 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.
