Type profiler by intercepting 'new' and 'delete' expressions.
It stores mapping between object's starting addresses and their
allocated types when a build option 'clang_type_profiler=1' is
specified. It enables information like
"an object at 0x37f3c88 is an instance of std::string."
Nothing is changed when the option is not specified.
It depends on a modified version of the LLVM/Clang compiler
introduced at deps/third_party/llvm-allocated-type.
BUG=123758
TEST=build with clang_type_profiler=1 and run type_profiler_unittests and type_profiler_map_unittests manually.
