util: Add a randomized test for the virtual memory allocator
The test pseudo-randomly makes allocations and deallocations with
the virtual memory allocator and checks that the results are
consistent. Specifically, we test that:
* no result from the allocator overlaps an already allocated range
* allocated memory fulfills the stated alignment requirement
* a failed result from the allocator could not have been fulfilled
* memory freed to the allocator can later be allocated again
v2: - fix if() in test() to actually run fill()
v3: - add c++11 build flag (Jason)
- test the full 64-bit range (Jason)
