Rewrite Error.prototype.toString in C++.
...
This avoids many back-and-forth calls to the runtime.
This also slightly changes the way we avoid getters. Previously, we circumvent getting the name property of ReferenceError, SyntaxError and TypeError due to crbug/69187 (in order to avoid leaking information from those errors through a 'name' getter installed on their prototypes). Now we do that for all errors created by V8.

Make Error.prototype.name writable again, as required by the spec and the web.
...
Address http://code.google.com/p/chromium/issues/detail?id=69187 by instead
ignoring getters on ReferenceError.prototype.name in Error.prototype.toString.
And while we're at it, do the same for SyntaxError and TypeError, and the
properties "message", "type", and "arguments" on all of them, which
potentially have similar issues.

Make the 'name' property on error prototypes read-only and dont-delete
...
to avoid leaking of error objects to accessor methods when formatting
error messages internally.
Also, do not call overwritten toString methods on error objects when
formatting messages internally.
