  -----------
  [CostModel][X86] Adjust sitofp/uitofp SSE/AVX legalized costs based on llvm-mca reports.

Update (mainly) vXi8/vXi16 -> vXf32/vXf64 sitofp/uitofp costs based on the worst case costs from the script in D103695.

Move to using legalized types wherever possible, which allows us to prune the cost tables.
