Rahul Joshi 9744606614 [MLIR] Change default builders generated by TableGen to use TypeRange for result types
- Change the default builders to use TypeRange instead of ArrayRef<Type>
- Custom builders defined in LinalgStructuredOps now conflict with the default
  separate param ones, but the default collective params one is still needed. Resolve
  this by replicating the collective param builder as a custom builder and skipping
  the generation of default builders for these ops.

Alex Zinenko c538169ee9 [mlir] Add insert before/after to list-like constructs in C API
Blocks in a region and operations in a block are organized in a linked list.
The C API only provides functions to append or to insert elements at the
specified numeric position in the list. The latter is expensive since it
requires to traverse the list. Add insert before/after functionality with low
cost that relies on the iplist elements being convertible to iterators.

Stella Laurenzo c1ded6a759 Add mlir python APIs for creating operations, regions and blocks.
* The API is a bit more verbose than I feel like it needs to be. In a follow-up I'd like to abbreviate some things and look in to creating aliases for common accessors.
* There is a lingering lifetime hazard between the module and newly added operations. We have the facilities now to solve for this but I will do that in a follow-up.
* We may need to craft a more limited API for safely referencing successors when creating operations. We need more facilities to really prove that out and should defer for now.

* Will re-add mutation more correctly in a follow-on.
* Eliminates the detached state on blocks and regions, simplifying the ownership hierarchy.

Stella Laurenzo 7abb0ff7e0 Add Operation to python bindings.
* Fixes a rather egregious bug with respect to the inability to return arbitrary objects from py::init (was causing aliasing of multiple py::object -> native instance).
* Makes Modules and Operations referencable types so that they can be reliably depended on.
* Uniques python operation instances within a context. Opens the door for further accounting.
* Next I will retrofit region and block to be dependent on the operation, and I will attempt to model the API to avoid detached regions/blocks, which will simplify things a lot (in that world, only operations can be detached).
* Added quite a bit of test coverage to check for leaks and reference issues.
* Supercedes: https://reviews.llvm.org/D87213

Mehdi Amini fb1de7ed92 Implement a new kind of Pass: dynamic pass pipeline

to run on the currently visited operation.
This feature can be used for example to implement a sub-pipeline that
would run only on an operation with specific attributes. Another example
would be to compute a cost model and dynamic schedule a pipeline based
on the result of this analysis.

I discovered this by looking the the failure stack trace. lld/ELF/symbolTable.cpp, SymbolTable::insert() hit into an assert with related to Epoch Trackers. The root cause is to due to there is no protection around the symMap (update) which is implemented in non-thread safe data structure: denseMap.

Nicolas Vasilache 93fd30bac3 [mlir][Linalg] Evolve named ops to use assembly form and support linalg on tensors.
This revision allows representing a reduction at the level of linalg on tensors for named ops. When a structured op has a reduction and returns tensor(s), new conventions are added and documented.

As an illustration, the syntax for a `linalg.matmul` writing into a buffer is:

```
  linalg.matmul ins(%a, %b : memref<?x?xf32>, tensor<?x?xf32>)
               outs(%c : memref<?x?xf32>)
```

, whereas the syntax for a `linalg.matmul` returning a new tensor is:

```
  %d = linalg.matmul ins(%a, %b : tensor<?x?xf32>, memref<?x?xf32>)
                    init(%c : memref<?x?xf32>)
                      -> tensor<?x?xf32>
```

Other parts of linalg will be extended accordingly to allow mixed buffer/tensor semantics in the presence of reductions.
