Replace nsJSUtils::EvaluateString calls by ExecutionContext scopes.
ExecutionContext: The mRetValue is not used even though it is checked in various asserts.
This is how it is in the Mozilla code even years later, only the passed in value is used.
ParseTask: JoinDecode() and JoinCompile() run the same code but the type is different
causing a debug assert when it checks the type Script vs ScriptDecode.

Support import from timeout handlers by associating the initiating script with the compiled JSScript.
Fix error message that covers all import() failures that don't throw a JS exception.

Partial - Replace nsJSUtils::EvaluateString calls by ExecutionContext scopes.
Left EvaluateString() in nsXBLProtoImplField.cpp until ExecutionContext errors can be fixed.

Since these are just interpreted comments, there's 0 impact on actual code.
This removes all lines that match /* vim: set(.*)tw=80: */ with S&R -- there are
a few others scattered around which will be removed manually in a second part.
