Change the convention for cost-centre labels to be <name>_cc and
cost-centre stacks to be <name>_ccs.  This makes cost-centre labels
more consistent with our other naming conventions, and fixes some
problems caused by cost-centre labels being misinterpreted by the
mangler.

This fixes one cause of profiled programs crashing; if you're seeing
this symptom then this patch may help.
