Fix seg fault handling template parameter expressions containing '<='

Browse source 
Recent commits ensure types are correctly stored in SwigType *. In
particular template parameters are enclosed within '<(' and ')>'.
Now we can confidently handle template parameters as really being
delimited as such to fix an infinite loop handling template expressions
containing '<' or '>'. The previous implementation only assumed
template parameters were delimited by '<' and '>'.
