Sanjay Patel 4127705ad2 [InstCombine] allow icmp (and X, C2), C1 folds for splat constant vectors
The code to calculate 'UsesRemoved' could be simplified.
As-is, that code is a victim of PR30273:

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.
