  Log Message:
  -----------
  [X86] Add more avx512 masked fmaddsub/fmsubadd autoupgrade tests with rounding control not set to 4.

The fmsubadd upgrade doesn't insert the negate properly when the
rounding control isn't 4.

  Log Message:
  -----------
  [X86] Correct the implementation of the avx512 masked fmsubadd autoupgrade code to not leave the negate unconnected.

This was causing us to generate fmaddsub instead of fmsubadd if
rounding control is not 4.
