Fix a heap profiling regression.

Browse Source 
Fix prof_tctx_comp() to incorporate tctx state into the comparison.
During a dump it is possible for both a purgatory tctx and an otherwise
equivalent nominal tctx to reside in the tree at the same time.

This regression was introduced by
602c8e0971160e4b85b08b16cf8a2375aa24bc04 (Implement per thread heap
profiling.).
