Do not stream redundant stuff
as discussed on IRC this adds knob to disable stuff we stream "just for
fun"
(or to make it easier to debug streamer desychnonization).
Te size of .o files in gcc subdirectory is reduced form 506MB to 492MB
gcc/
* lto-streamer-out.c (lto_output_tree): Add streamer_debugging check.
* lto-streamer.h (streamer_debugging): New constant
* tree-streamer-in.c (streamer_read_tree_bitfields): Add
streamer_debugging check.
(streamer_get_pickled_tree): Likewise.
* tree-streamer-out.c (pack_ts_base_value_fields): Likewise.
