Added support for API accessors that prohibit overwriting by accessors defined in JavaScript code by using __defineGetter__ and __defineSetter__.
Improved handling of conditionals in test status files.
Introduced access control in propertyIsEnumerable.
Improved performance of some string operations by caching information about the type of the string between operations.
Fixed bug in fast-case code for switch statements that only have integer labels.
