Normalizing memrefs failed when a caller of symbolic use in a function
can not be casted to `CallOp`. This patch avoids the failure by checking
the result of the casting. If the caller can not be casted to `CallOp`,
it is skipped.

Allow propagating optional user defined attributes during SCF to GPU conversion. Gives opportunity to use user defined attributes in the further lowering. For example setting subgroup size, or other options for GPU dispatch. This does not break backward compatibility and does not require new attributes, just allow passing optional ones.

This patch moves the memory space field from MemRefType and UnrankedMemRefType

This pass converts shape.cstr_* ops to eager (side-effecting)

Fixed an error when deserializing the SPIR-V binary
to MLIR SPIR-V. Before, the SPIR-V dialect was not loaded

Conversion to LLVM becomes confusing and incorrect if someone tries to lower
STD -> LLVM and only then GPULaunchFuncOp to LLVM separately. Although it is
technically allowed now, it works incorrectly because of the argument
promotion. The correct way to use this conversion pattern is to add to the
STD->LLVM patterns before running the pass.

This tweaks the generated code for parsing attributes with a custom
directive to call `addAttribute` on the `OperationState` directly,
and adds a newline after this call. Previously, the generated code
would call `addAttribute` on the `OperationState` field `attributes`,
which has no such method and fails to compile. Furthermore, the lack
of newline would generate code with incorrectly formatted single line
`if` statements. Added tests for parsing and printing attributes with
a custom directive.

- Change the default builders to use TypeRange instead of ArrayRef<Type>
- Custom builders defined in LinalgStructuredOps now conflict with the default

this by replicating the collective param builder as a custom builder and skipping
the generation of default builders for these ops.

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.

* 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.

* 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.

Instead of performing a transformation, such pass yields a new 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.
