Description of detection logic

IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsRegressionBase: Marked as regression because the compare was 5% greater than the baseline, and the value was not too small.
IsRegressionChecked: Marked as regression because the three check build points were 0.05 greater than the baseline.
IsRegressionWindowed: Marked as regression because 162.02969826731444 > 66.73839345022085.
IsChangePoint: Marked as a change because one of 3/1/2023 3:09:21 PM, 3/2/2023 11:15:04 AM, 3/17/2023 10:06:19 AM, 5/18/2023 7:10:13 PM, 5/23/2023 2:36:40 AM falls between 5/14/2023 5:56:01 AM and 5/23/2023 2:36:40 AM.
IsRegressionStdDev: Marked as regression because -35.22640229692167 (T) = (0 -166.37180313726515) / Math.Sqrt((3.553203917439853 / (26)) + (158.42157583000204 / (19))) is less than -2.016692199226234 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (26) + (19) - 2, .025) and -1.6067524465823098 = (63.8233996309829 - 166.37180313726515) / 63.8233996309829 is less than -0.05.
IsImprovementBase: Marked as not an improvement because the compare was not 5% less than the baseline, or the value was too small.
IsChangeEdgeDetector: Marked not as a regression because Edge Detector said so.

@kg looks like one of your changes. I see that it improved partially after, could you take a look?

[kg]

Yeah, I think the codegen is bad for certain uses of vectors which causes this. It improved some with optimizations I made later to 16-byte-sized copies but it's still kind of bad. A few of these are at least really blatant examples we can hopefully look at and fix.
