Seth Brenith 0a31d508f1 [tools] Teach v8_debug_helper where heap spaces start in ptr-compr mode
v8_debug_helper attempts to flag known object pointers when it can
recognize them, even if the memory pointed to is not available in the
crash dump. In ptr-compr builds, the first pages of the map space,
read-only space, and old space are always at the same offsets within the
heap reservation region, so we can more easily detect known objects.
