This commit renames 4 pattern rewriter API functions:
* `updateRootInPlace` -> `modifyOpInPlace`
* `startRootUpdate` -> `startOpModification`
* `finalizeRootUpdate` -> `finalizeOpModification`
* `cancelRootUpdate` -> `cancelOpModification`
The term "root" is a misnomer. The root is the op that a rewrite pattern
matches against
(https://mlir.llvm.org/docs/PatternRewriter/#root-operation-name-optional).
A rewriter must be notified of all in-place op modifications, not just
in-place modifications of the root
(https://mlir.llvm.org/docs/PatternRewriter/#pattern-rewriter). The old
function names were confusing and have contributed to various broken
rewrite patterns.
Note: The new function names use the term "modify" instead of "update"
for consistency with the `RewriterBase::Listener` terminology
(`notifyOperationModified`).
Those methods were added long time ago. Now we get the same methods generated by tablegen, so there is no need for duplicates.

Now that dialect constructors are generated in the .cpp file, we can
drop all of the dependent dialect includes from the .h file.

This patch removes an old recursive implementation to lower vector.transpose to extract/insert operations
and replaces it with a iterative approach that leverages newer linearization/delinearization utilities.
The patch should be NFC except by the order in which the extract/insert ops are generated.

This reduces the dependencies of the MLIRVector target and makes the dialect consistent with other dialects.

After removing the range type, Linalg does not define any type. The revision thus consolidates the LinalgOps.h and LinalgTypes.h into a single Linalg.h header. Additionally, LinalgTypes.cpp is renamed to LinalgDialect.cpp to follow the convention adopted by other dialects such as the tensor dialect.

After removing the last LinalgOps that have no region attached we can verify there is a region. The patch performs the following changes:
- Move the SingleBlockImplicitTerminator trait further up the the structured op base class.
- Adapt the LinalgOp verification since the trait only check if there is 0 or 1 block.
- Introduce a getBlock method on the LinalgOp interface.
- Access the LinalgOp body using either getBlock() or getBody() if the concrete operation type is known.
This patch is a follow up to https://reviews.llvm.org/D111233.

Add a helper method to check if an index vector contains a permutation of its indices. Additionally, refactor applyPermutationToVector to take int64_t.

Instead of interchanging loops during the loop lowering this pass performs the interchange by permuting the indexing maps. It also updates the iterator types and the index accesses in the body of the operation.

This reverts commit 511dd4f4383b1c2873beac4dbea2df302f1f9d0c along with
a couple fixes.
Original message:
Now the context is the first, rather than the last input.
This better matches the rest of the infrastructure and makes
it easier to move these types to being declaratively specified.

This revision drops init_tensor arguments from Linalg on tensors and instead uniformizes the output buffers and output tensors to be consistent.
This significantly simplifies the usage of Linalg on tensors and is a stepping stone for
its evolution towards a mixed tensor and shape abstraction discussed in https://llvm.discourse.group/t/linalg-and-shapes/2421/19.

Linalg transformations are currently exposed as DRRs.
Unfortunately RewriterGen does not play well with the line of work on named linalg ops which require variadic operands and results.
Additionally, DRR is arguably not the right abstraction to expose compositions of such patterns that don't rely on SSA use-def semantics.
This revision abandons DRRs and exposes manually written C++ patterns.
Refactorings and cleanups are performed to uniformize APIs.
This refactoring will allow replacing the currently manually specified Linalg named ops.
A collateral victim of this refactoring is the `tileAndFuse` DRR, and the one associated test, which will be revived at a later time.
Lastly, the following 2 tests do not add value and are altered:
- a dot_perm tile + interchange test does not test anything new and is removed
- a dot tile + lower to loops does not need 2-D tiling and is trimmed.
