Sanjay Patel fc164bf317 [InstCombine] remove constant by inverting compare + logic (PR27105) 
https://llvm.org/bugs/show_bug.cgi?id=27105

We can check if all bits outside of a constant mask are set with a 
single constant.

As noted in the bug report, although this form should be considered the
canonical IR, backends may want to transform this into an 'andn' / 'andc' 
comparison against zero because that could be a single machine instruction.

This directory contains test cases for the instcombine transformation.  The
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.
