SgLabel Usage

Here is how one can create labels:

     SgLabelSymb * foo = new SgLabelSymb("foo", *s);
     SgLabel * foolab = new SgLabel(*foo);
     SgLabelStmt * ls = new SgLabelStmt(*foolab, *s);

Note that s is of type SgStatement *, and is the scope of the label statement.

So here are the steps for using labels:

1. create a symbol
2. create a label
3. create a label statement
4. insert the label statement before the appropriate statement
