  [AArch64][SVE] NFC: extend tests for flag-setting predicate instructions

A follow on patch will extend existing

  PTEST(PG, OP(PG, ...)) -> OP_FLAG_SETTING(PG, ...)

optimization in AArch64InstrInfo::optimizePTestInstr to cover more of
the flag-setting instructions

  Log Message:
  -----------
  [AArch64][SVE] Use more flag-setting instructions

If OP in PTEST(PG, OP(PG, ...)) has a flag-setting variant change the
opcode so the PTEST becomes redundant. This patch extends this existing
optimization in AArch64::optimizePTestInstr to cover all flag-setting
opcodes.
