12e41d9264 [mlir][bufferize] Infer memref types when possible
Instead of recomputing memref types from tensor types, try to infer them when possible. This results in more precise layout maps.

eda6f907d2 [mlir][NFC] Shift a bunch of dialect includes from the .h to the .cpp
Now that dialect constructors are generated in the .cpp file, we can
drop all of the dependent dialect includes from the .h file.

Insert a cast if the two tensors with identical layout (that are passed to `arith.select`) have different layout maps after bufferization.

77eee5795e [mlir] Refactor DialectRegistry delayed interface support into a general DialectExtension mechanism
The current dialect registry allows for attaching delayed interfaces, that are added to attrs/dialects/ops/etc.
when the owning dialect gets loaded. This is clunky for quite a few reasons, e.g. each interface type has a
separate tracking structure, and is also quite limiting. This commit refactors this delayed mutation of
dialect constructs into a more general DialectExtension mechanism. This mechanism is essentially a registration
callback that is invoked when a set of dialects have been loaded. This allows for attaching interfaces directly
on the loaded constructs, and also allows for loading new dependent dialects. The latter of which is
extremely useful as it will now enable dependent dialects to only apply in the contexts in which they
are necessary. For example, a dialect dependency can now be conditional on if a user actually needs the
interface that relies on it.

1f971e23f0 [mlir] Trim a huge number of unnecessary dependencies on the Func dialect
The Func has a large number of legacy dependencies carried over from the old
Standard dialect, which was pervasive and contained a large number of varied
operations. With the split of the standard dialect and its demise, a lot of lingering
dead dependencies have survived to the Func dialect. This commit removes a
large majority of then, greatly reducing the dependence surface area of the
Func dialect.

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

585a8a321c [mlir][bufferize] OpOperands can have multiple aliasing OpResults
This makes getAliasingOpResult symmetric to getAliasingOpOperand. The previous implementation was confusing for users and implemented in such a way only because there are currently no bufferizable ops that have multiple aliasing OpResults.

cdb7675c26 [mlir][bufferize][NFC] Make PostAnalysisSteps a function

ab47418df6 [mlir][bufferize] Merge tensor-constant-bufferize into arith-bufferize
The bufferization of arith.constant ops is also switched over to BufferizableOpInterface-based bufferization. The old implementation is deleted. Both implementations utilize GlobalCreator, now renamed to just `getGlobalFor`.

GlobalCreator no longer maintains a set of all created allocations to avoid duplicate allocations of the same constant. Instead, `getGlobalFor` scans the module to see if there is already a global allocation with the same constant value.

For compatibility reasons, it is still possible to create a pass that bufferizes only `arith.constant`. This pass (createConstantBufferizePass) could be deleted once all users were switched over to One-Shot bufferization.

4157455425 [mlir][Pass] Deprecate FunctionPass in favor of OperationPass<FuncOp>
The only benefit of FunctionPass is that it filters out function
declarations. This isn't enough to justify carrying it around, as we can
simplify filter out declarations when necessary within the pass. We can
also explore with better scheduling primitives to filter out declarations
at the pipeline level in the future.

The definition of FunctionPass is left intact for now to allow time for downstream
users to migrate.

be1aeb818c Remove NaN constant from arith.minf, arith.maxf expansion
If any of the operands is NaN, return the operand instead of a new constant.

When the rhs operand is a constant, the second arith.cmpf+select ops will be folded away.

https://reviews.llvm.org/D117010 marks the two ops commutative, which will place the constant on the rhs.

8165eaa885 [mlir](arithmetic) Add ceildivui to the arithmetic dialect
The specific description is [[ https://llvm.discourse.group/t/adding-unsigned-integer-ceil-and-floor-in-std-dialect/4541 | Adding unsigned integer ceil in Std Dialect ]] .

When we lower ceilDivOp this will generate below code, sometimes we know m and n are unsigned intergal.Here are some redundant judgments about positive and negative.
So we need to add some unsigned operations to simplify the instructions.
```
ceilDiv(n, m)
  x = (m > 0) ? -1 : 1
  return (n*m>0) ? ((n+x) / m) + 1 : - (-n / m)
```
unsigned operations:
```
ceilDivU(n, m)
  return n ==0 ?  0 :  ((n - 1) / m) + 1
```

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)
