  Log Message:
  -----------
  [sanitizer] Construct InternalMmapVector without memory allocation.

Construction of InternalMmapVector is often followed by a call to
reserve(), which may result in immediate reallocation of the memory
for the internal storage. This patch delays that allocation until
it is really needed.
