Version 1.3.5
Optimize initialization of some arrays in the builtins.
Fix mac-nm script to support filenames with spaces.
Support for using the V8 profiler when V8 is embedded in a Windows DLL.
Changed typeof RegExp from 'object' to 'function' for compatibility. Fixed bug where regexps were not callable across contexts.
Added context independent script compilation to the API.
Added API call to get the stack trace for an exception.
Added API for getting object mirrors.
Make sure that SSE3 instructions are used whenever possible even when running off a snapshot generated without using SSE3 instructions.
Tweaked the handling of the initial size and growth policy of the heap.
Added native code generation for RegExp to 64-bit version.
Added JavaScript debugger support to 64-bit version.
