Version 3.6.0
Fixed a bug when optimizing named function expression (issue 1647).
Fixed a bug when optimizing f.call.apply (issue 1650).
Made arguments and caller always be null on native functions (issues 1548 and 1643).
Fixed issue 1648 (cross-compiling x64 targeting ia32).
Fixed issue 371 (d8 printing of strings containing \0).
Fixed order of evaluation in arguments to parseInt (issue 1649).
Fixed a problem with large heap snapshots in Chrome DevTools (issue 1658, chromium issue 89268).
Upped default maximum heap size from 512M to 700M.
