[PATCH] D16360: unordered_map: Avoid unnecessary mallocs when no insert occurs

[Duncan P. N. Exon Smith via cfe-commits]

Honestly I didn't think much about the testing style.  I used r239666
as a reference and modified it for std::unordered_map.

I'll redo the tests when I have a moment, based on the newer examples.
Probably next week some time?
