Hi Martin,

Hi Kris,
nice. Maybe consider grouping lines 1246 to 1264 together. You could either rearrange the conditions so that BoolTest gets tested last and split there, thus reusing three lines. Probably no improvement. Done. I swapped the order of the two operands to the Cmp for the second pattern, so I didn't want to merge these patterns. But per your suggestion, I swapped it back and it still works, so we get to save a couple of lines.
Webrev updated in place.
Thanks, Kris
