Version 3.18.3

Exposed the GC under a name that is less collision prone than window.gc. (issue 2641)

Do not emit double values at their use sites. (Chromium issue 234101)

Added methods to allow resuming execution after calling TerminateExecution(). (issue 2361)

Performance and stability improvements on all platforms.
