8226721: Missing intrinsics for Math.ceil, floor, rint

[Eric Caspole]

Hi Jatin,
I have a few comments on the JMH in the webrev:

1 - Make the TESTSIZE into a JMH Param, so it will be more versatile:

   public final int TESTSIZE = 1024;

becomes:

   @Param({"1024"})
   public int testSize;


2 - the DspecialVals is not used at all

   public final double[] DspecialVals = {
       0.0, -0.0, Double.NaN, Double.NEGATIVE_INFINITY, 
Double.POSITIVE_INFINITY};



Thanks for including the JMH from start with your webrev.
Eric
