We run MemoryContextStats() when we fail to allocate memory, including during
abort processing after a previous error. So I think it qualifies for being
somewhat special. Thus I suspect check_stack_depth() wouldn't be a good idea -
but we could make the stack_is_too_deep() path simpler and just return in the
existing MemoryContextStatsInternal() when that's the case.
