    d: Return the correct value for C++ constructor calls (PR101664)

    C++ constructors return void, even though the front-end semantic treats
    them as implicitly returning `this'.  To handle this correctly, the
    object reference is cached and used as the result of the expression.

            PR d/101664

    gcc/d/ChangeLog:

            * expr.cc (ExprVisitor::visit (CallExp *)): Use object expression
as
            result for C++ constructor calls.

    gcc/testsuite/ChangeLog:

            * gdc.dg/extern-c++/extern-c++.exp: New.
            * gdc.dg/extern-c++/pr101664.d: New test.
            * gdc.dg/extern-c++/pr101664_1.cc: New test.
