  [riscv] Add tests for vsetvli reuse across iterations of a loop

These variations are chosen to exercise both FRE and PRE cases involving loops which don't change state in the iteration and can thus perform vsetvli in the preheader of the loop only.  At the moment, these are essentially all TODOs.
