That will help us when creating C libraries.

It implements a C library which records information about the memory allocations.
The library is loaded using the LD_PRELOAD mechanism (and DYLD_INSERT_LIBRARIES
for osx).

GoogleBenchmark displays the memory allocation results are only in the json
format. For instance:

DYLD_FORCE_FLAT_NAMESPACE=1 DYLD_INSERT_LIBRARIES=./lib/Instrumentation/libRBInstrumentation.dylib ./root/interpreter/InterpreterLookupHelperBenchmarks --benchma
rk_format=json:
