Two chromium unit tests reported phony errors when run on wine on valgrind because RtlAllocateHeap sometimes returned an allocation without notifying valgrind about it.
RtlReAllocateHeap is also missing valgrind notifications for the large block paths. It also appears that the function leaks memory in the realloc small -> large path.
