Version 3.18.0
Enabled pretenuring of fast literals in high promotion mode.
Removed preparser library; link preparser executable against full V8.
Fixed set-up of intrinsic's 'constructor' properties. (Chromium issue 229445)
ES6 symbols: extended V8 API to support symbols (issue 2158).
Removed ARM support for VFP2.
Made __proto__ a real JavaScript accessor property. (issue 1949 and issue 2606)
Performance and stability improvements on all platforms.
