RISC-V/testsuite: Add cases for integer SFB cond-move operations

Verify, for short forward branch targets and the conditional-move
operations that already work as expected, that if-conversion triggers
via `noce_try_cmove' already at `-mbranch-cost=1' and that extraneous
instructions such as SNEZ, etc. are not present in output.  Cover all
integer relational operations to make sure no corner case escapes.
