These macros do not always kill the process, and sometimes it would be nice to know if some match or not, and how many times (especially for the CHECK_IF one). This commit adds a new section "dbg_cnt" made of structs that contain function name, file name, line number, check type, condition and match count. A newe macro __DBG_COUNT() adds one to the counter, and is placed inside _BUG_ON() and _BUG_ON_ONCE(). It's worth noting that the exact type of the check is not very precise but in practice we don't care, as most checks will cause the process to die anyway unless they're of type _BUG_ON_ONCE() (used by CHECK_IF by default). All of this is limited to !defined(USE_OBSOLETE_LINKER) because we're creating a section, thus we need a modern linker to be able to scan this section later. Doing so adds ~50kB to the executable due to the ~1266 BUG_ON() and others placed there. That's not huge in comparison to the visibility it can provide.
