    fortran: defer class wrapper initialization after deallocation [PR92178]

    If an actual argument is associated with an INTENT(OUT) dummy, and code
    to deallocate it is generated, generate the class wrapper initialization
    after the actual argument deallocation.

    This is achieved by passing a cleaned up expression to
    gfc_conv_class_to_class, so that the class wrapper initialization code
    can be isolated and moved independently after the deallocation.

            PR fortran/92178

    gcc/fortran/ChangeLog:

            * trans-expr.cc (gfc_conv_procedure_call): Use a separate gfc_se
            struct, initalized from parmse, to generate the class wrapper.
            After the class wrapper code has been generated, copy it back
            depending on whether parameter deallocation code has been
            generated.

    gcc/testsuite/ChangeLog:

            * gfortran.dg/intent_out_19.f90: New test.
