statistics with checking enabled and using longs to count bytes

Using the patch from

http://gcc.gnu.org/ml/gcc-patches/2008-09/msg01270.html

I gathered statistics using 64-bit longs for this test case. Using it, one
finds that 10,292,897,120 bytes of bitmaps and 6,449,831,120 bytes in
alloc-pools are allocated with mainline for this test case (at least when
checking is enabled).
