RISC-V/testsuite: Add branched cases for GEU and LEU cond-move operations

Verify, for Ventana and Zicond targets and the GEU and LEU
conditional-move operations, that if-conversion does *not* trigger at
`-mbranch-cost=3' setting, which makes original branched code sequences
cheaper than their branchless equivalents if-conversion would emit.
