[FIX] tools.graph: stop useless recursions to make graph_get() faster
In some cases (depending on the kind of graph being rendered),
the recursive processing could lead to timings of 1 minute per
call to ir.ui.view.graph_get(), even for a relatively small
number of nodes (e.g. 10). By avoiding useless recursions in
head_component() it goes down to a few ms.
This patch also adds str() wrappers for __str__ and printing
of nodes labels, which are not necessarily strings (they
are often integers)
