Version 3.16.3
Improved GC performance when moving parts of a FixedArray (issue 2452).
Enabled readline on d8 while building a shared lib (issue 1781).
Fixed missing exception check in typed array constructor (Chromium issue 168545).
Check for read-only-ness when preparing for array sort (issue 2419).
Performance and stability improvements on all platforms.
