[mlir][linalg] Replace linalg.fill by OpDSL variant.
The revision removes the linalg.fill operation and renames the OpDSL generated linalg.fill_tensor operation to replace it. After the change, all named structured operations are defined via OpDSL and there are no handwritten operations left.
A side-effect of the change is that the pretty printed form changes from:
```
%1 = linalg.fill(%cst, %0) : f32, tensor<?x?xf32> -> tensor<?x?xf32>
```
changes to
```
%1 = linalg.fill ins(%cst : f32) outs(%0 : tensor<?x?xf32>) -> tensor<?x?xf32>
```
Additionally, the builder signature now takes input and output value ranges as it is the case for all other OpDSL operations:
```
rewriter.create<linalg::FillOp>(loc, val, output)
```
changes to
```
rewriter.create<linalg::FillOp>(loc, ValueRange{val}, ValueRange{output})
```
All other changes remain minimal. In particular, the canonicalization patterns are the same and the `value()`, `output()`, and `result()` methods are now implemented by the FillOpInterface.

[clang-format] Minimize the damage caused by AlignArrayOfStructures when working on non square arrays
I have lost count of the number of times this has been reported, but it fundamentally comes down to the fact that the "AlignArrayLeft/Right" function is fundamentally broken for non-square arrays.
As a result, a pointer can end up running off the end of the array structure, I've spent the last 2 weekends trying to rewrite this algorithm but I've struggled to get it aligned correctly.
This is an interim fix, that ignores all array that are non-square and leaves them alone. I think this can allow us to close out most of the crashes (if not all).
I think this can help reduce the number of bugs coming in that are duplicates.
