These came in from the Google-internal version of tcmalloc. They saw some
decent speed improvements, both on microbenchmarks and big programs. The
idea is to improve the speed of the "Is everything initialized?" type of
code, that's at the start of all allocations and deallocations.

defined in a windows SDK somewhere.
