The existing vector.transpose lowering patterns only triggers if the
input vector is 2D. The revision extends the pattern to handle n-D
vectors which are effectively 2-D vectors (e.g., vector<1x4x1x8x1).
It refactors a common check about 2-D vectors from X86Vector
lowering to VectorUtils.h so it can be reused by both sides.

Replace references to enumerate results with either result_pairs
(reference wrapper type) or structured bindings. I did not use
structured bindings everywhere as it wasn't clear to me it would
improve readability.
This is in preparation to the switch to zip semantics which won't
support non-const lvalue reference to elements:
https://reviews.llvm.org/D144503.
I chose to use values instead of const lvalue-refs because MLIR is
biased towards avoiding `const` local variables. This won't degrade
performance because currently `result_pair` is cheap to copy (size_t
+ iterator), and in the future, the enumerator iterator dereference
will return temporaries anyway.

Plain `getVectorType()` can be quite confusing and error-prone
given that, well, vector ops always work on vector types, and
it can commonly involve both source and result vectors. So this
commit makes various such accessor methods to be explicit w.r.t.
source or result vectors.

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

This has been on _Both for a couple of weeks. Flip usages in core with
intention to flip flag to _Prefixed in follow up. Needed to add a couple
of helper methods in AffineOps and Linalg to facilitate a pure flag flip
in follow up as some of these classes are used in templates and so
sensitive to Vector dialect changes.

The AVX2 lowering for transpose operations is only applicable to f32 vector types.

The existing AVX2 lowering patterns for the transpose op only triggers if the
input vector is 2-D. This patch extends the patterns to trigger for n-D vectors
which are effectively 2-D vectors (e.g., vector<1x4x1x8x1). The main constraint
for the generalized AVX2 patterns to be applicable to these vectors is that the
dimensions that are greater than one must be transposed. Otherwise, the existing
patterns are not applicable.

This revision adds enough support to allow InlineAsmOp to work properly with indirect memory constraints "*m".
These require an explicit "elementtype" TypeAttr on the operands to pass LLVM verification and need to be provided.

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