Michael ,
Please excuse me if I missed some email thread on llvm-dev describing at the high level what you are doing with MPX. 
If there was no such thread I encourage you to start one.

I am personally extremely skeptical about anything related to MPX
(see https://github.com/google/sanitizers/wiki/AddressSanitizerIntelMemoryProtectionExtensions and the more recent and detailed intel-mpx.github.io).
Now, from a quick glance it looks like you are using the MPX instructions for something else,
but it deserves a discussion before we look at the patches.
