[gcc(refs/vendors/riscv/heads/gcc-13-with-riscv-opts)] RISC-V/testsuite: Add branched cases for generic integer cond moves

[Jeff Law]

https://gcc.gnu.org/g:4ab9cb07db575e0fed30255b9a4e57a0e4ccb8e8

commit 4ab9cb07db575e0fed30255b9a4e57a0e4ccb8e8
Author: Maciej W. Rozycki <macro@embecosm.com>
Date:   Wed Nov 22 01:18:28 2023 +0000

    RISC-V/testsuite: Add branched cases for generic integer cond moves
    
    Verify, for generic integer conditional-move operations, if-conversion
    *not* to trigger at the respective sufficiently low `-mbranch-cost='
    settings that make original branched code sequences cheaper than their
    branchless equivalents if-conversion would emit.  Cover all integer
    relational operations to make sure no corner case escapes.
