File src/bootstrapper.cc (right):

src/bootstrapper.cc:307: Handle<JSFunction> throw_type_error_function;
Nit: can we somehow rename this to make it more consistent with the new one?

src/bootstrapper.cc:1430: Handle<Map> strict_mode_generator_function_map =
Nit: for consistency, drop _mode_ here, too.

This should probably include tests to check the properties while the respective
function is actually active on the call stack.
