nit: Mixing comment styles between C++ (//) and C (/* */) between here and line
10.

Based on the C++ Style guide, and that this is necessarily C++ code, it would
seem like this should be // ALLOCATED_TYPE_MAP_H_ , however, I defer to TCMalloc
convention.

Good catch.  Thanks.  (It might come from heap-profiler.h.  But, we should
follow Chromium's guideline in completely new files.)
