  Log Message:
  -----------
  [RISCV][LV] Use predicate-else-scalar-epilogue flag in tail folding tests. NFC

Align the tests closer with what we eventually intend to enable by
default on RISC-V by using
-prefer-predicate-over-epilogue=predicate-else-scalar-epilogue, instead
of dropping vectorization entirely with predicate-dont-vectorize.

Also adjust the non-EVL run lines so that they use
-prefer-predicate-over-epilogue=scalar-epilogue instead of
-force-tail-folding-style=none, so we're only using testing one type of
flag instead of a combination of two.
