RISC-V/testsuite: Add branchless cases for T-Head non-equality cond moves

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.
