  -----------
  [X86] Adjust some IceLake integer shuffle schedule classes (PR48110)

The IceLake scheduler model is still mainly a copy of the SkylakeServer model.

This patch adjusts the integer shuffle classes to account for most instructions now working on Port 1 as well as Port 5.

This is based off Agner + uops.info as well as the PR48110 report.
