Support: mapped_file_region: Pass MAP_NORESERVE to mmap
This allows mapping larger files, delaying OOM failures until too many
pages of them are accessed. This is makes the behavior of the
mapped_file_region in this regard consistent between its "Unix" and
"Windows" implementations.
Guard the code witih #if defined(MAP_NORESERVE), consistent with other
uses of MAP_NORESERVE in llvm-project, because some FreeBSD versions do
not provide this flag.
