b0abd4893f [llvm] Add missing StringExtras.h includes
In preparation for removing the `#include "llvm/ADT/StringExtras.h"`
from the header to source file of `llvm/Support/Error.h`, first add in
all the missing includes that were previously included transitively
through this header.

b9a907d133 Convert MLIR IndentedOstream to header only.
This class has been causing me no end of grief for a long time, and the way it is used by mlir-tblgen is technically an ODR violation in certain situations.

Due to the way that the build is layered, it is important that the MLIR tablegen libraries only depend on the LLVM tablegen libraries, not on anything else (like MLIRSupport). It has to be this way because these libraries/binaries are special and must pre-exist the full shared libraries. Therefore, the dependency chain must be clean (and static).

At some point, someone pulled out a separate build target for just IndendedOstream in an attempt to satisfy the constraint. But because it is weird in different ways, this target was never installed properly as part of distributions, etc -- this causes problems for downstreams seeking to build a tblggen binary that doesn't itself have ODR/shared library problems.

I was attempting to fix the distribution stuff but just opted to collapse this into a header-only library and not try to solve this with build layering. I think this is the safest and the least bad thing for such a dep. This also makes for a clean comment that actually explains the constraint (which I was having trouble verbalizing with the weird subset dependency).

68f58812e3 [mlir] Move casting calls from methods to function calls
The MLIR classes Type/Attribute/Operation/Op/Value support
cast/dyn_cast/isa/dyn_cast_or_null functionality through llvm's doCast
functionality in addition to defining methods with the same name.
This change begins the migration of uses of the method to the
corresponding function call as has been decided as more consistent.

Note that there still exist classes that only define methods directly,
such as AffineExpr, and this does not include work currently to support
a functional cast/isa call.

Context:
- https://mlir.llvm.org/deprecation/ at "Use the free function variants
  for dyn_cast/cast/isa/…"
- Original discussion at https://discourse.llvm.org/t/preferred-casting-style-going-forward/68443

Implementation:
This patch updates all remaining uses of the deprecated functionality in
mlir/. This was done with clang-tidy as described below and further
modifications to GPUBase.td and OpenMPOpsInterfaces.td.

Steps are described per line, as comments are removed by git:
0. Retrieve the change from the following to build clang-tidy with an
   additional check:
   main...tpopp:llvm-project:tidy-cast-check
1. Build clang-tidy
2. Run clang-tidy over your entire codebase while disabling all checks
   and enabling the one relevant one. Run on all header files also.
3. Delete .inc files that were also modified, so the next build rebuilds
   them to a pure state.

```

Note that there still exist classes that only define methods directly,

Caveats include:
- This clang-tidy script probably has more problems.
- This only touches C++ code, so nothing that is being generated.

Context:
- https://mlir.llvm.org/deprecation/ at "Use the free function variants
  for dyn_cast/cast/isa/…"
- Original discussion at https://discourse.llvm.org/t/preferred-casting-style-going-forward/68443

Implementation:
This first patch was created with the following steps. The intention is
to only do automated changes at first, so I waste less time if it's
reverted, and so the first mass change is more clear as an example to
other teams that will need to follow similar steps.

Steps are described per line, as comments are removed by git:
0. Retrieve the change from the following to build clang-tidy with an
   additional check:
   https://github.com/llvm/llvm-project/compare/main...tpopp:llvm-project:tidy-cast-check
1. Build clang-tidy
2. Run clang-tidy over your entire codebase while disabling all checks
   and enabling the one relevant one. Run on all header files also.
3. Delete .inc files that were also modified, so the next build rebuilds
   them to a pure state.
4. Some changes have been deleted for the following reasons:
   - Some files had a variable also named cast
   - Some files had not included a header file that defines the cast
     functions
   - Some files are definitions of the classes that have the casting
     methods, so the code still refers to the method instead of the
     function without adding a prefix or removing the method declaration
     at the same time.

7f00ba08aa Restore mlir-opt --run-reproducer option to opt-in running a reproducer
When tooling out there produces a reproducer that is archived, the first thing
a user is likely to expect is to process this as they do with any MLIR file.
However https://reviews.llvm.org/D126447 changed the behavior of mlir-opt to
eliminate the `--run-reproducer` option and instead automatically run it when
present in the input file. This creates a discrepancy in how mlir-opt behaves
when fed with an input file, and is surprising for users.
The explicit passing of `--run-reproducer` to express user-intent seems more
in line with what is expected from `mlir-opt`.

8ac8c922fb [mlir][irdl] Add IRDL registration

```mlir
module {

      %0 = irdl.is f32
      %1 = irdl.is f64

      irdl.parameters(%2)

      %1 = irdl.parametric @complex<%0>
      irdl.operands(%1)
      irdl.results(%0)
    }
}
```

the IRDL file can be loaded with the `mlir-opt --irdl-file=dialect.irdl`
command, and the following file can then be parsed:

```mlir
func.func @conorm(%p: !cmath.complex<f32>, %q: !cmath.complex<f32>) -> f32 {
  %norm_p = "cmath.norm"(%p) : (!cmath.complex<f32>) -> f32
  %norm_q = "cmath.norm"(%q) : (!cmath.complex<f32>) -> f32
  %pq = arith.mulf %norm_p, %norm_q : f32
  return %pq : f32
}
```

To minimize the size of this patch, the operation, attribute, and type verifier are all always returning `success()`.

One handler will handle the action or it'll cascade to other handlers.

This model does not really fit the current evolution of the Action tracing
and debugging: we can't foresee a good case where this behavior compose with
the use-case behind the handlers. Instead we simplify it with a single

This makes round-trip tests easier, since existing import/export passes can be reused and no combined round-trip passes have to be registered (example: mlir-translate  -serialize-spirv -deserialize-spirv).

Additionally, by leveraging TranslateRegistration with file-to-file TranslateFunctions, generic pre- and post-processing can be added before/after conversion to/from MLIR.

d7daa6364c [mlir][tblgen] Emit deprecation warning if kEmitRawAttributes is used
As discussed in https://reviews.llvm.org/D140886, emitting a warning if the old API is used may be beneficial to encourage migration to the new fold API.
This reuse the existing `Deprecated` infrastructure within TableGen, and simply marks the `def` for `kEmitRawAttributesFolder` causing a use of it in a record (even if set within a base class) to emit a warning.

Error message as printed in the terminal:
```

65684dc6a7 [mlir][ods] Rework how transitive use of deprecated defs are handled
The code currently attempting to recursively find uses of a deprecated def has a few deficiences:
* It recurses into all def uses. This is problematic as it also causes any users of a def using a deprecated def, to be considered deprecated, causing a transitive chain of deprecated defs (see `H_ButNotTransitivelyInNonAnonymousDef` in test case for reproducer)
* It did not recurse into other kinds of fields, such as list and DAGs

This patch fixes the issue by reworking the code to properly recurse into inits and not to recurse into def uses unless they are anonymous defs. Since inits (including DAG, List and anonymous defs) are uniqued, the memoization is kept and remains profitable.

2140260d91 [mlir] Remove remaining uses of llvm::Optional (NFC)
This patch removes one "using" declaration and #include
"llvm/ADT/Optional.h".  It keeps several "using" declarations in
headers for downstream users.

This is part of an effort to migrate from llvm::Optional to
std::optional:

0a81ace004 [mlir] Use std::optional instead of llvm::Optional (NFC)
This patch replaces (llvm::|)Optional< with std::optional<.  I'll post
a separate patch to remove #include "llvm/ADT/Optional.h".

a1fe1f5f77 [mlir] Add #include <optional> (NFC)
This patch adds #include <optional> to those files containing
llvm::Optional<...> or Optional<...>.

I'll post a separate patch to actually replace llvm::Optional with
std::optional.
