commit r14-5727-g4111bdf99bf5c54b13e7d484fe4b75661d04a4e0

RISC-V/testsuite: Add branchless cases for generic integer cond moves
Verify, for generic integer conditional-move operations, if-conversion
to trigger via `noce_try_cmove' at the respective sufficiently high
`-mbranch-cost=' settings that make branchless code sequences produced
by if-conversion cheaper than their original branched equivalents, and,
where applicable, that extraneous instructions such as SNEZ, etc. are
not present in output. Cover all integer relational operations to make
sure no corner case escapes.
