Bumping to GCC6 has a tracking bug:
This would give us general c++14 capability.

The only blocker I know of is updating Sixgill's (hazard analysis?)
GCC version: https://bugzilla.mozilla.org/show_bug.cgi?id=1444543
If there are no other blockers, upgrading our GCC required version may
follow relatively quickly.
