58ceae9561 [mlir:NFC] Remove the forward declaration of FuncOp in the mlir namespace
FuncOp has been moved to the `func` namespace for a little over a month, the
using directive can be dropped now.

4a3460a791 [mlir:FunctionOpInterface] Rename the "type" attribute to "function_type"
This removes any potential confusion with the `getType` accessors
which correspond to SSA results of an operation, and makes it
clear what the intent is (i.e. to represent the type of the function).

23aa5a7446 [mlir] Rename the Standard dialect to the Func dialect
The last remaining operations in the standard dialect all revolve around
FuncOp/function related constructs. This patch simply handles the initial
renaming (which by itself is already huge), but there are a large number
of cleanups unlocked/necessary afterwards:

* Removing a bunch of unnecessary dependencies on Func
* Cleaning up the From/ToStandard conversion passes
* Preparing for the move of FuncOp to the Func dialect

ace01605e0 [mlir] Split out a new ControlFlow dialect from Standard
This dialect is intended to model lower level/branch based control-flow constructs. The initial set
of operations are: AssertOp, BranchOp, CondBranchOp, SwitchOp; all split out from the current
standard dialect.

c75cedc237 [Coroutines] Set presplit attribute in Clang and mlir
This fixes bug49264.

Simply, coroutine shouldn't be inlined before CoroSplit. And the marker
for pre-splited coroutine is created in CoroEarly pass, which ran after
AlwaysInliner Pass in O0 pipeline. So that the AlwaysInliner couldn't
detect it shouldn't inline a coroutine. So here is the error.

This patch set the presplit attribute in clang and mlir. So the inliner
would always detect the attribute before splitting.

cfb72fd3a0 [mlir] Switch arith, llvm, std & shape dialects to accessors prefixed both form.
Following
https://llvm.discourse.group/t/psa-ods-generated-accessors-will-change-to-have-a-get-prefix-update-you-apis/4476,
this follows flipping these dialects to _Both prefixed form. This
changes the accessors to have a prefix. This was possibly mostly without
breaking breaking changes if the existing convenience methods were used.

(https://github.com/jpienaar/llvm-project/blob/main/clang-tools-extra/clang-tidy/misc/AddGetterCheck.cpp
was used to migrate the callers post flipping, using the output from
Operator.cpp)

Precursor: https://reviews.llvm.org/D110200

Removed redundant ops from the standard dialect that were moved to the

Renamed all instances of operations in the codebase and in tests.

b54c724be0 [mlir:OpConversionPattern] Add overloads for taking an Adaptor instead of ArrayRef
This has been a TODO for a long time, and it brings about many advantages (namely nice accessors, and less fragile code). The existing overloads that accept ArrayRef are now treated as deprecated and will be removed in a followup (after a small grace period). Most of the upstream MLIR usages have been fixed by this commit, the rest will be handled in a followup.

9a5bc83660 Add an escape-hatch for conversion of funcs with blocking awaits to coroutines.
Currently TFRT does not support top-level coroutines, so this functionality will allow to have a single blocking await at the top level until TFRT implements the necessary functionality.

6ea22d4626 Optionally eliminate blocking runtime.await calls by converting functions to coroutines.
Interop parallelism requires needs awaiting on results. Blocking awaits are bad for performance. TFRT supports lightweight resumption on threads, and coroutines are an abstraction than can be used to lower the kernels onto TFRT threads.

Specify the `!async.group` size (the number of tokens that will be added to it) at construction time. `async.await_all` operation can potentially race with `async.execute` operations that keep updating the group, for this reason it is required to know upfront how many tokens will be added to the group.

973ddb7d6e Define a NoTerminator traits that allows operations with a single block region to not provide a terminator
In particular for Graph Regions, the terminator needs is just a
historical artifact of the generalization of MLIR from CFG region.
Operations like Module don't need a terminator, and before Module
migrated to be an operation with region there wasn't any needed.

To validate the feature, the ModuleOp is migrated to use this trait and
the ModuleTerminator operation is deleted.

This patch is likely to break clients, if you're in this case:

- you may iterate on a ModuleOp with `getBody()->without_terminator()`,
  the solution is simple: just remove the ->without_terminator!
- you created a builder with `Builder::atBlockTerminator(module_body)`,
  just use `Builder::atBlockEnd(module_body)` instead.
- you were handling ModuleTerminator: it isn't needed anymore.
- for generic code, a `Block::mayNotHaveTerminator()` may be used.
