While working on an integration, I found a lot of inconsistencies on IR printing and verification. It turns out that we were:
* Only doing "soft fail" verification on IR printing of Operation, not of a Module.
* Failed verification was interacting badly with binary=True IR printing (causing a TypeError trying to pass an `str` to a `bytes` based handle).
* For systematic integrations, it is often desirable to control verification yourself so that you can explicitly handle errors.
This patch:
* Trues up the "soft fail" semantics by having `Module.__str__` delegate to `Operation.__str__` vs having a shortcut implementation.
* Fixes soft fail in the presence of binary=True (and adds an additional happy path test case to make sure the binary functionality works).
* Adds an `assume_verified` boolean flag to the `print`/`get_asm` methods which disables internal verification, presupposing that the caller has taken care of it.
It turns out that we had a number of tests which were generating illegal IR but it wasn't being caught because they were doing a print on the `Module` vs operation. All except two were trivially fixed:
* linalg/ops.py : Had two tests for direct constructing a Matmul incorrectly. Fixing them made them just like the next two tests so just deleted (no need to test the verifier only at this level).
* linalg/opdsl/emit_structured_generic.py : Hand coded conv and pooling tests appear to be using illegal shaped inputs/outputs, causing a verification failure. I just used the `assume_verified=` flag to restore the original behavior and left a TODO. Will get someone who owns that to fix it properly in a followup (would also be nice to break this file up into multiple test modules as it is hard to tell exactly what is failing).
Notes to downstreams:
* If, like some of our tests, you get verification failures after this patch, it is likely that your IR was always invalid and you will need to fix the root cause. To temporarily revert to prior (broken) behavior, replace calls like `print(module)` with `print(module.operation.get_asm(assume_verified=True))`.

Previously, in case there was only one `Optional` operand/result within
the list, we would always return `None` from the accessor, e.g., for a
single optional result we would generate:
```
return self.operation.results[0] if len(self.operation.results) > 1 else None
```
But what we really want is to return `None` only if the length of
`results` is smaller than the total number of element groups (i.e.,
the optional operand/result is in fact missing).
This commit also renames a few local variables in the generator to make
the distinction between `isVariadic()` and `isVariableLength()` a bit
more clear.

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.

Extend the OpDSL syntax with an optional `domain` function to specify an explicit dimension order. The extension is needed to provide more control over the dimension order instead of deducing it implicitly depending on the formulation of the tensor comprehension. Additionally, the patch also ensures the symbols are ordered according to the operand definitions of the operation.
