Version 3.5.1.

Fixed setting the readonly flag on the prototype property using the API call FunctionTemplate::SetPrototypeAttributes (issue 1539).

Changed the tools/test.py script to use d8 instead of shell for testing.

Fixed crash in ToBooleanStub when GC happens during invocation.

Enabled automatic unboxing of double arrays.

Performance improvements on all platforms.
