This CL makes lowering to loops always be a:
```
%D = linalg.dim %view, constant : !linalg.view<...>
affine.for %ix = %c0 to %D {
...
}
```
This form composes correctly with tiling and is also the proper way to emit loops from views that across function boundaries.
The previous version that would extract the range_min/max/step was composing incorrectly with tiling (i.e. would shift by range_min both in the loop bounds and in the slice) and would not work across function boundaries.
The relevant tests are updated and a new test `dot_view`---which lowers to loops from views passed as function parameters---is added.
When additional context is available, the linalg.dim operations should be folded away but this is left for a future CL.
