Nicolas Vasilache 424041ad58 Add EDSC sugar ...

This allows load, store and ForNest to be used with both Expr and Bindable.
This simplifies writing generic pieces of MLIR snippet.

For instance, a generic pointwise add can now be written:

```cpp
// Different Bindable ivs, one per loop in the loop nest.
auto ivs = makeBindables(shapeA.size());
Bindable zero, one;
// Same bindable, all equal to `zero`.
SmallVector<Bindable, 8> zeros(ivs.size(), zero);
// Same bindable, all equal to `one`.
SmallVector<Bindable, 8> ones(ivs.size(), one);
// clang-format off
Bindable A, B, C;
Stmt scalarA, scalarB, tmp;
Stmt block = edsc::Block({
  ForNest(ivs, zeros, shapeA, ones, {
    scalarA = load(A, ivs),
    scalarB = load(B, ivs),
    tmp = scalarA + scalarB,
    store(tmp, C, ivs)
  }),
});
// clang-format on
```

This CL also adds some extra support for pretty printing that will be used in
a future CL when we introduce standalone testing of EDSCs. At the momen twe
are lacking the basic infrastructure to write such tests.
