to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
UBSan needs to check if memory snippet it's going to print resides
in addressable memory. Similar check might be helpful in ASan with
dump_instruction_bytes option (see http://reviews.llvm.org/D5167).
Instead of scanning /proc/self/maps manually, delegate this check to
the OS kernel: try to write this memory in a syscall and assume that
memory is inaccessible if the syscall failed (e.g. with EFAULT).
Fixes PR20721.
