    fortran: Support clobbering with implicit interfaces [PR105012]

    Before procedure calls, we clobber actual arguments whose associated
    dummy is INTENT(OUT).  This only applies to procedures with explicit
    interfaces, as the knowledge of the interface is necessary to know
    whether an argument has the INTENT(OUT) attribute.

    This change also enables clobber generation for procedure calls without
    explicit interface, when the procedure has been defined in the same
    file because we can use the dummy arguments' characteristics from the
    procedure definition in that case.

    The knowledge of the dummy characteristics is directly available through
    gfc_actual_arglist=C3=A2s associated_dummy pointers which have been pop=
ulated
    as a side effect of calling gfc_check_externals.

            PR fortran/105012

    gcc/fortran/ChangeLog:

            * trans-expr.cc (gfc_conv_procedure_call): Use dummy
            information from associated_dummy if there is no information
            from the procedure interface.

    gcc/testsuite/ChangeLog:

            * gfortran.dg/intent_optimize_5.f90: New test.
