(#168066)
This patch adds `ub` as a dependent dialect to `memref`, and uses
`ub.poison` as the default value in `AllocaOp::getDefaultValue` for the
mem2reg pass.
This aligns the behavior of `mem2reg` with LLVM, where loading a value
before having a value should be poison.

These are identified by misc-include-cleaner. I've filtered out those
that break builds. Also, I'm staying away from llvm-config.h,
config.h, and Compiler.h, which likely cause platform- or
compiler-specific build failures.

implementation (#145230)
Previously running `-generate-runtime-verification` on an IR containing
`memref.reinterpret_cast` would crash because its implementation of the
`RuntimeVerifiableOpInterface` was removed in
https://github.com/llvm/llvm-project/pull/132547 but its associated
entry in `declarePromisedInterface` was never removed.
This causes an error when you try and run
`-generate-runtime-verification` on an IR containing
`memref.reinterpret_cast` that looks like
```
LLVM ERROR: checking for an interface (`mlir::RuntimeVerifiableOpInterface`) that was promised by dialect 'memref' but never implemented. This is generally an indication that the dialect extension implementing the interface was never registered.
```
as reported in https://github.com/llvm/llvm-project/issues/144028.
In this PR I also added all the ops that do have implementations of this
interface in
`mlir/lib/Dialect/MemRef/Transforms/RuntimeOpVerification.cpp` to the
`declarePromisedInterface` for consistency.

Reorder the template operands of `declarePromisedInterface()` to match
`declarePromisedInterfaces()`.

This PR adds promised interface declarations for all interfaces declared
in `InitAllDialects.h`.
Promised interfaces allow a dialect to declare that it will have an
implementation of a particular interface, crashing the program if one
isn't provided when the interface is used.

This PR adds promised interface declarations for
`ConvertToLLVMPatternInterface` in all the dialects that support the
`ConvertToLLVM` dialect extension.
Promised interfaces allow a dialect to declare that it will have an

This diff makes findDealloc return nullopt if the list of users contains "realloc".
Fixes https://github.com/llvm/llvm-project/issues/60726
(In particular, in SimplifyClones (uses findDealloc) treating "realloc" as "dealloc"
breaks the assumption that "dealloc" has no users)

This patch replaces (llvm::|)Optional< with std::optional<. I'll post
a separate patch to remove #include "llvm/ADT/Optional.h".
This is part of an effort to migrate from llvm::Optional to
std::optional:

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

The patch adds operations to `BlockAndValueMapping` and renames it to `IRMapping`. When operations are cloned, old operations are mapped to the cloned operations. This allows mapping from an operation to a cloned operation. Example:
```
Operation *opWithRegion = ...
Operation *opInsideRegion = &opWithRegion->front().front();
IRMapping map
Operation *newOpWithRegion = opWithRegion->clone(map);
Operation *newOpInsideRegion = map.lookupOrNull(opInsideRegion);
```
Migration instructions:
All includes to `mlir/IR/BlockAndValueMapping.h` should be replaced with `mlir/IR/IRMapping.h`. All uses of `BlockAndValueMapping` need to be renamed to `IRMapping`.

This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated. The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.

NFC. Clean up memref utils library. This library had a single function
that was completely misplaced. MemRefUtils is expected to be (also per
its comment) a library providing analysis/transforms utilities on memref
dialect ops or memref types. However, in reality it had a helper that
was depended upon by the MemRef dialect, i.e., it was a helper for the
dialect ops library and couldn't contain anything that itself depends on
the MemRef dialect. Move the single method to the memref dialect that
will now allow actual utilities depending on the memref dialect to be
placed in it.
Put findDealloc in the `memref` namespace. This is a pure move.

These are among the last operations still defined explicitly in C++. I've
tried to keep this commit as NFC as possible, but these ops
definitely need a non-NFC cleanup at some point.

Remove `getDynOperands` and `createOrFoldDimOp` from MemRef.h to decouple MemRef a bit from Tensor. These two functions are used in other dialects/transforms.

* Split memref.dim into two operations: memref.dim and tensor.dim. Both ops have the same builder interface and op argument names, so that they can be used with templates in patterns that apply to both tensors and memrefs (e.g., some patterns in Linalg).
* Add constant materializer to TensorDialect (needed for folding in affine.apply etc.).
* Remove some MemRefDialect dependencies, make some explicit.

* Previously, we were only generating .h.inc files. We foresee the need to also generate implementations and this is a step towards that.
* Discussed in https://llvm.discourse.group/t/generating-cpp-inc-files-for-dialects/3732/2
* Deviates from the discussion above by generating a default constructor in the .cpp.inc file (and adding a tablegen bit that disables this in case if this is user provided).
* Generating the destructor started as a way to flush out the missing includes (produces a link error), but it is a strict improvement on its own that is worth doing (i.e. by emitting key methods in the .cpp file, we root vtables in one translation unit, which is a non-controversial improvement).

The patch in question broke the build with shared libraries due to
missing dependencies, one of which would have been circular between
MLIRStandard and MLIRMemRef if added. Fix this by moving more code
around and swapping the dependency direction. MLIRMemRef now depends on
MLIRStandard, but MLIRStandard does _not_ depend on MLIRMemRef.
Arguably, this is the right direction anyway since numerous libraries
depend on MLIRStandard and don't necessarily need to depend on
MLIRMemref.
Other otable changes include:
- some EDSC code is moved inline to MemRef/EDSC/Intrinsics.h because it
creates MemRef dialect operations;
- a utility function related to shape moved to BuiltinTypes.h/cpp
because it only realtes to shaped types and not any particular dialect
(standard dialect is erroneously believed to contain MemRefType);
- a Python test for the standard dialect is disabled completely because
the ops it tests moved to the new MemRef dialect, but it is not
exposed to Python bindings, and the change for that is non-trivial.
