[PATCH] UBSan on Windows

[Timur Iskhodzhanov]

Hi Aaron,

See also http://reviews.llvm.org/D5368 – Amine has made some progress
on UBSan lately as well, but didn't quite finish it.

Can you please send the review via phab?

Comments:
* Your implementation of atomic_exchange doesn't seem to be atomic?
* lib/ubsan/ubsan_value.h – please update the comment
* Does check-ubsan (?) work?
* Have you tried Win64?
