[16/44] RISC-V/testsuite: Add branchless cases for GEU and LEU cond-move operations
Checks
Commit Message
Verify, for Ventana and Zicond targets and the GEU and LEU
conditional-move operations, that if-conversion triggers via
`noce_try_cmove' at `-mbranch-cost=4' setting, which makes branchless
code sequences produced by if-conversion cheaper than their original
branched equivalents, and that extraneous instructions such as SEQZ,
etc. are not present in output.
