Sanjay Patel cbf458f9f0 [InstCombine] add tests to show missed canonicalization of min/max; NFC
Unfortunately, recognizing these in value tracking may cause us to hit
a hack in InstCombiner::visitICmpInst() more often:
http://lists.llvm.org/pipermail/llvm-dev/2017-January/109340.html

...but besides being the obviously Right Thing To Do, there's a clear 
codegen win from identifying these patterns for several targets.

dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
