  [CostModel][X86] Convert AVX1/SSE41 SREM/SDIV by constants to cost tables

When adding cost kind support it will be easier to maintain these if we're not calculating on the fly

  -----------
  [CostModel][X86] getArithmeticInstrCost - move SLM reduceVMULWidth cost handling into the generic MUL handling

This is still SLM specific atm, but converting this to more closely match the codegen from reduceVMULWidth should be straightforward
