Subject: [PATCH] Turn on hardened mode and alias absl types to STL types..

The absl implementations contain various hardening checks where the
standard is UB. At the time, libc++ lacked corresponding hardening
checks, so we forced the use of absl types. As of
https://crbug.com/1335422, this is no longer true. Switching to the STL
version of variant is tracked by https://crbug.com/1373620.
