Revert of Safe numeric library: base/numerics (copied from Chromium)

Revert of Safe numeric library: base/numerics (copied from Chromium) (patchset #11 id:250001 of https://codereview.webrtc.org/1753293002/ )

Reason for revert:
Looks like the Chrome iOS build is broken because of these two changes.  So I'm going to have to revert.  Here's the error:
