[llvm] r216523 - InstCombine: Optimize GEP's involving ptrtoint better

The buildbot failure is:


Unfortunately it is also just in SPASS, so it probably doesn't provide much help in
producing an isolated test case.

Can you point me to a specific broken bot log?

I was trying to reduce a case from the SPASS failure on ARM, but the
program is multi-file and creduce doesn't play well with it. Other
manual techniques didn't fare well either, as the problem disappeared
very easily. If you had a smaller (or at least a single-file) example,
that'd help a lot.
