  Log Message:
  -----------
  [compiler-rt] check max address from kernel is <= mmap range size

If these sizes do not match, asan will not work as expected. Previously, we added compile-time checks for non-iOS platforms. We check at run time for iOS because we get the max VM size from the kernel at run time.
