Nicolas Vasilache 67b10532c6 [mlir][Vector] Allow a 0-d for for vector transfer ops.
This revision updates the op semantics, printer, parser and verifier to allow 0-d transfers.
Until 0-d vectors are available, such transfers have a special form that transits through vector<1xt>.
This is a stepping stone towards the longer term work of adding 0-d vectors and will help significantly reduce corner cases in vectorization.

Transformations and lowerings do not yet support this form, extensions will follow.

Nicolas Vasilache 31270eb165 [mlir][Vector] Let vector.multi_reduction reduce down to a scalar.
vector.multi_reduction currently does not allow reducing down to a scalar.
This creates corner cases that are hard to handle during vectorization.
This revision extends the semantics and adds the proper transforms, lowerings and canonicalizations to allow lowering out of vector.multi_reduction to other abstractions all the way to LLVM.

In a future, where we will also allow 0-d vectors, scalars will still be relevant: 0-d vector and scalars are not equivalent on all hardware.

In the process, splice out the implementation patterns related to vector.multi_reduce into a new file.

Emilio Cota 57c56cf20c X86Vector: relax checks in rsqrt's integration test
Instead of hard-coding results for both Intel and AMD, let's relax
the checks to simplify the test while supporting both implementations.
Note that:
- If a new hardware implementation comes up in the future, it is likely
  to pass the relaxed tests, i.e. no future maintenance burden for us.
- If something terribly wrong happens (e.g. instead of rsqrt we
  execute 1/sqrt), the tests will probably catch it, since the relaxed
  tests expect low precision (e.g. rsqrt(1) != 1.0).

Matthias Springer f8453ea75f [mlir][linalg][bufferize] Rewrite "write into non-writable memory" detection

The main idea is that there is a conflict in the case of inplace bufferization if:

1. Someone writes to (an alias of) opOperand, opResult or the to-be-bufferized op writes itself.
2. And, opOperand or opResult aliases a non-writable buffer.

Alex Zinenko b164f23c29 [mlir][python] support taking ops instead of values in op constructors
Introduce support for accepting ops instead of values when constructing ops. A
single-result op can be used instead of a value, including in lists of values,
and any op can be used instead of a list of values. This is similar to, but
more powerful, than the C++ API that allows for implicitly casting an OpType to
Value if it is statically known to have a single result - the cast in Python is
based on the op dynamically having a single result, and also handles the
multi-result case. This allows to build IR in a more concise way:

    op = dialect.produce_multiple_results()
    other = dialect.produce_single_result()
    dialect.consume_multiple_results(other, op)

instead of having to access the results manually

    op = dialect.produce.multiple_results()
    other = dialect.produce_single_result()
    dialect.consume_multiple_results(other.result, op.operation.results)

The dispatch is implemented directly in Python and is triggered automatically
for autogenerated OpView subclasses. Extension OpView classes should use the
functions provided in ods_common.py if they want to implement this behavior.
An alternative could be to implement the dispatch in the C++ bindings code, but
it would require to forward opaque types through all Python functions down to a
binding call, which makes it hard to inspect them in Python, e.g., to obtain
the types of values.
