  -----------
  [X86] Ensure 256-bit sqrt + crosslane shuffles are set to 2 uops + half rate

Fixes another mismatch between the D103695 script and the znver1 scheduler model

Confirmed with the AMD SoG, Agner + instlatx64

  Log Message:
  -----------
  [X86] Fix simd integer ALU and shuffle port allocations

znver1/2 uses pipes0/1/3 for most integer ALU and nearly all integer/float shuffles occur on pipes1/2

More cleanup work to hopefully get shuffle kinds costs testing added to the D103695 script sometime soon

Confirmed with the AMD SoG, Agner + instlatx64
