Heap Profiling -------------- This commit adds simple hp2ps-style heap profiling. Just the '-h' option is supported so far. Heap profiles will show the top two cost centres on each cost centre stack. Time/Alloc profiles have been extended to aggregate the costs on a per-cost-centre basis and show the table of highest consuming cost centres before the full table of cost centre stacks. Profiles work best if '-caf-all' is used, especially when using one of the '-auto' flags.
