MFC r237624, r237714, r237716, r237860:Bring llquantize support into Dtrace.Bryan Cantrill implemented the equivalent of semi-log graphpaper for Dtrace so llquantize will use one logarithmic andone linear scale.
Import the dtrace llquantize test files from the vendor area.Now that we have an illumos vendor area, import the llquantizetest files directly from there to make it easier to track thecode provenance.Special thanks to Martin Matuska for populating the illumosvendor area.Requested by: obrien
Update illumos/dist to revision 13742:b6bbdd77139cZFS bits will follow in a separate commit
