That this is HeapVector<> backing store isn't encoded in the type name; should
it be?

[hajimehoshi, 2016/03/03 10:12:31]

I tried to pass HeapVectorBacking<T, VectorTraits<T>> to
WTF_HEAP_PROFILER_TYPE_NAME but this didn't work because of the comma. Using
braces also didn't work. I had to use ::WTF::getStringWithTypeName directly...

Done.

"#define COMMA ," or a local 'using/typedef' alias doesn't work out?

[hajimehoshi, 2016/03/04 06:39:14]

Thanks. 'using' worked. Done.

Ditto, but for HeapHashTable<> backing store.
