[MERGE #4922 @sethbrenith] Allow GrowingArray to be used with RecyclerNonLeafAllocator

Merge pull request #4922 from sethbrenith:user/sethb/growing-array-recycler

While prototyping another change that I've since discarded, I discovered that attempting to use a GrowingArray with a RecyclerNonLeafAllocator would quietly allocate the array as a leaf object anyway, and cause catastrophic failures later on. This change doesn't affect current behavior (and I verified that the compiled binary didn't change), but prevents anyone from falling into the same trap.
