Verify, for T-Head targets and the non-equality integer conditional-move operations, that if-conversion triggers via `noce_try_cmove' at `-mbranch-cost=2' setting, which makes branchless code sequences produced by if-conversion cheaper than their original branched equivalents, and that extraneous instructions such as SNEZ, etc. are not present in output.
