  [X86] getIntrinsicInstrCost - begin generalizing BSWAP load/store-folding handling.

Move load/store folding 'free costs' inside the adjustTableCost helper so we can some additional intrinsics in the future.

The plan is to do something similar for other costs callbacks as well (getArithmeticInstrCost etc.).

  Log Message:
  -----------
  [DAG] visitAVG - avoid duplication in the avg(ext(x), ext(y)) -> ext(avg(x, y)) folds

m_BinOp doesn't need a compile time opcode - so we can merge these into signed/unsigned cases.
