    Fix internal error on lambda function

    This boils down to the RTL expander trying to take the address of a DECL
    whose RTX is a register.

    gcc/
            PR c++/90448
            * calls.c (initialize_argument_information): When the argument
            is passed by reference, do not make a copy in a thunk only if
            the argument is already in memory.  Remove redundant test for
            the case of callee copy.=
