fschneider@google.com cd54507fc2 Mark native functions when they are created.
Until now the parser marked native functions as native when parsing.

This may be too late for some functions. E.g. the native typed list
constructor may not be invoked because the intrinsic code is executed
instead (unless for example new-space allocation fails).

This causes missing type information when optimizing functions using
those recognized factory functions like Uint8List._new.
