  -----------
  [X86] Split 128 and 256-bit PTEST combines

We are missing SSE41 test coverage (and in fact have a bug with a PTEST->TESTP fold that is only valid on AVX).

  Log Message:
  -----------
  [X86] Only fold PTEST->TESTP on AVX targets

While PTEST is a SSE41 instruction, TESTPS/TESTPD was only added for AVX
