[PATCH] D20084: [sanitizer] Initial implementation of a Hardened Allocator

[Kostya Kortchinsky via llvm-commits]

cryptoad updated this revision to Diff 58659.
cryptoad added a comment.

With this diff ends the renaming process, so unless I missed or misunderstood something, this should be compliant with the LLVM coding standards.
Additional, I migrated the thread local PRNG initialization to use /dev/urandom for seeding purposes. This appears to not have significantly impacted the performances.
