Is this "BASE"? Sorry, I don't know how it's called in the headers in the same
directory.

E.g. heap-checker is not in base/BASE, but it uses BASE_HEAP_CHECKER_H_.  It
might come from its original code.

Ok, there's no consistency in this directory.  I use just
"ALLOCATED_TYPE_MAP_H_" here.  What do you think?
