af366593a4 Improve ExtractSymbols (pprof). 
Iterated downward through both libraries and PCs.  This allows PCs
to resolve even when library address ranges overlap.

ec5344eba2 Optimize ExtractSymbols (pprof). 
Modify ExtractSymbols to operate on sorted PCs and libraries, in order
to reduce computational complexity from O(N*M) to O(N+M).

a91f210929 Import pprof from google-perftools, svn r91. 
Fix divide-by-zero error in pprof.  It is possible for sample contexts
to currently have no associated objects, but the cumulative statistics
are still useful, depending on how the user invokes pprof.  Since
jemalloc intentionally does not filter such contexts, take care not to
divide by 0 when re-scaling for v2 heap sampling.

Install pprof as part of 'make install'.

Update pprof documentation.
