Previously there were two separate implementations of the same
initialization code, one in object.cc and one in interpreter.cc.
Now they both use Object::InitializeHeader.
Make TryAllocate a static method of Interpreter instead of a file-local
function in interpreter.cc so that it gets access to the private method
Object::InitializeHeader.
TEST=ci (just code refactoring)
