Verify, for generic integer conditional-move operations, if-conversion *not* to trigger at the respective sufficiently low `-mbranch-cost=' settings that make original branched code sequences cheaper than their branchless equivalents if-conversion would emit. Cover all integer relational operations to make sure no corner case escapes.
