Simplify LTO section format.
2019-07-22 Martin Liska <mliska@suse.cz>
* lto-section-in.c (lto_get_section_data):
Use new function get_compression.
* lto-streamer-out.c (produce_lto_section): Use
set_compression to encode compression algorithm.
* lto-streamer.h (struct lto_section): Do not
use bitfields in the format.
