Issue #1691 - Part 7e: Dependencies for required to finish part 7d. https://bugzilla.mozilla.org/show_bug.cgi?id=1331662 Reimplement EvaluateString using the ExecutionContext class. https://bugzilla.mozilla.org/show_bug.cgi?id=1316078 Extract redudant code into StartOffThreadParseTask. Use an ExclusiveContext instead of a JSContext in XDR functions. Add a script decoder as a valid off-main-thread parse-task. https://bugzilla.mozilla.org/show_bug.cgi?id=900784 Add nsJSUtils functions for encoding and decoding the bytecode. https://bugzilla.mozilla.org/show_bug.cgi?id=1316081 Add XDRIncrementalEncoder to replace delazified LazyScript in the encoded XDR buffer. Add an XDRIncrementalEncoder instance on the ScriptSource. Expose a new JSAPI to incrementally encode bytecode when it is generated. https://bugzilla.mozilla.org/show_bug.cgi?id=1334091 XDR function use the sourceObject instead of the enclosingScript as argument.
