The name of the function set through Function::SetName() is only used for
information. The name is used when printing the function using toString(),
in stack-traces, in debugger and in profiling. The JavaScript scope where
the function not bound is not affected. It is like the following JavaScript:
a = function b(){}
Property a is a function with name b, a.name === 'b', and property b is not
defined.
