Gerald Squelart 0af4548b10 Bug 1520103 - Fixed non-unified Profiler build - r=mstange
Found issues by forcing a local non-unified build.

Also sorted #includes by logical groups (from most local to most global), and
alphabetically within groups.

Depends on D18621

Differential Revision: https://phabricator.services.mozilla.com/D18622
