_leaf_helpers.erb: some functions are not leaf

If a function has rb_warning() that is not a leaf because warning
ultimately is a method call of Warning#warn.

If a function has rb_name_error() that is not a leaf because
NameError is allocated, then initialized.  This of course
involves calling NameError#initialize.
