I noticed while working on another CL that the watchermain (equivalent of chromemain) for chrome_watcher.dll does not register the dumpwithoutcrashing function with base::debug::SetDumpWithoutCrashingFunction

This would mean that calling base::debug::DumpWithoutCrashing for code running in chrome_watcher.dll would do nothing. I don't know the impact of this, since perhaps it never gets called.

Aside, perhaps we should consider adding a DCHECK in DumpWithoutCrashing if dump_without_crashing_function_ is nullptr, since this is normally not what we want...?
