Kostya Kortchinsky 2ba105a7da [sanitizer] Update scudo to use new API 
Summary:
The ScudoAllocator uses a SecondaryHeader to keep track of the size and base address of each mmap'd chunk.

This aligns well with what the ReservedAddressRange is trying to do.  This changeset converts the scudo allocator from using the MmapNoAccess/MmapFixed APIs to the ReservedAddressRange::Init and ::Map APIs.  In doing so, it replaces the SecondayHeader struct with the ReservedAddressRange object.

This is part 3 of a 4 part changeset; part 1 https://reviews.llvm.org/D39072 and part 2 https://reviews.llvm.org/D38592
