HeapProfiler: replace pointer based matching algorithm with string matching algorithm for strings_ member.

pros: decreased snapshot size.
cons: increased serialization time.

I've tested the implementation on gmail 90mb heap.
I saw no speed degradation on the serialization step.
The snapshot size lost ~3% of its size. 100Mb -> 97Mb.
