Balaram Makam 94ee5ea0aa "Reapply r268521 "[InstCombine] Canonicalize icmp instructions based on dominating conditions.""
This reapplies commit r268521, that was reverted in r268530 due to a test failure in select-implied.ll
Modified the test case to reflect the new change.

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.
