    d: Fix ICE on explicit immutable struct import [PR108877]

    Const and immutable types are built as variants of the type they are
    derived from, and TYPE_STUB_DECL is not set for these variants.

            PR d/108877

    gcc/d/ChangeLog:

            * imports.cc (ImportVisitor::visit (EnumDeclaration *)): Call
            make_import on TYPE_MAIN_VARIANT.
            (ImportVisitor::visit (AggregateDeclaration *)): Likewise.
            (ImportVisitor::visit (ClassDeclaration *)): Likewise.
