Original issue's description:
> Patch to try dump-on-DCHECK.
>
> This patch does two things:
>
> 1. Adds a flag to switch DCHECK from logging, dumping, and then crashing the process, to only uploading a crash dump, and only on the first failed DCHECK in each process.
>
> 2. Forces that flag, and DCHECK_ALWAYS_ON, on in Windows official builds.
>
> All non-debug e.g. CHECK behaviours remain unchanged; the intended effect is for DCHECKs to switch from no-ops to uploading dumps without crashing, in Windows official builds.
>
> Note that this CL is intended to be landed, a branch cut to release from, and then immediately reverted; it is not intended to be landed in Chromium for any longer period.
