calls.c (expand_call): Remove current_call_is_indirect nonsense.

        * calls.c (expand_call): Remove current_call_is_indirect nonsense.
        Add additional argument to INIT_CUMULATIVE_ARGS.
        (emit_library_call): Likewise.
        (emit_library_call_value): Likewise.
        * expr.c (expand_builtin): Likewise.
        * function.c (assign_parms): Likewise.
        * config/pa/pa.h (hppa_args): New field "indirect".
        (INIT_CUMULATIVE_ARGS): Initialize "indirect" field.
        (FUNCTION_ARG): Check "indirect" field, rather than
        "current_call_is_indirect".
        * All other backends updated with new argument to
        INIT_CUMULATIVE_ARGS
