RISC-V/testsuite: Add branched cases for FP cond-move operations

Verify, for Ventana and Zicond targets and the ordered floating-point
conditional-move operations that already work as expected, that
if-conversion does *not* trigger at `-mbranch-cost=2' setting, which
makes original branched code sequences cheaper than their branchless
equivalents if-conversion would emit.  Cover all ordered floating-point
relational operations to make sure no corner case escapes.
