Serge Guelton d94f70fb98 [mlir] Improve LLVM shlib support
mlir-tblgen was incompatible with libLLVM, due to explicit linkage with
libLLVMSupport etc.
As it cannot link with libLLVM, make sure all lib it uses are not using libLLVM
either.

As a side effect, also remove some explicit references to LLVM libs and use

MaheshRavishankar c694588fc5 [mlir][Linalg] Add pattern to tile and fuse Linalg operations on buffers.
The pattern is structured similar to other patterns like
LinalgTilingPattern. The fusion patterns takes options that allows you
to fuse with producers of multiple operands at once.
- The pattern fuses only at the level that is known to be legal, i.e
  if a reduction loop in the consumer is tiled, then fusion should
  happen "before" this loop. Some refactoring of the fusion code is
  needed to fuse only where it is legal.
- Since the fusion on buffers uses the LinalgDependenceGraph that is
  not mutable in place the fusion pattern keeps the original
  operations in the IR, but are tagged with a marker that can be later
  used to find the original operations.

This change also fixes an issue with tiling and
distribution/interchange where if the tile size of a loop were 0 it
wasnt account for in these.

Manually-defined named ops do not currently support `init_tensors` or return values and may never support them. Add extra interface to the StructuredOpInterface so that we can still write op-agnostic transformations based on StructuredOpInterface.

This is an NFC extension in preparation for tiling on tensors.

This revision allows representing a reduction at the level of linalg on tensors for named ops. When a structured op has a reduction and returns tensor(s), new conventions are added and documented.

As an illustration, the syntax for a `linalg.matmul` writing into a buffer is:

```
  linalg.matmul ins(%a, %b : memref<?x?xf32>, tensor<?x?xf32>)
               outs(%c : memref<?x?xf32>)
```

, whereas the syntax for a `linalg.matmul` returning a new tensor is:

```
  %d = linalg.matmul ins(%a, %b : tensor<?x?xf32>, memref<?x?xf32>)
                    init(%c : memref<?x?xf32>)
                      -> tensor<?x?xf32>
```

Other parts of linalg will be extended accordingly to allow mixed buffer/tensor semantics in the presence of reductions.

of size either 3(vectorized) or 1(not) as underlying vectors have to be of static
shape as well. In this commit we add support for convolutions of any size as well as
dynamic shapes by leveraging existing matmul infrastructure for tiling of both input

In the future this pass can be extended to take "tiling mask" as a user input which
will enable vectorization of user specified dimensions.

Alex Zinenko 855ec517a3 [mlir] Model StringRef in C API
Numerous MLIR functions return instances of `StringRef` to refer to a
non-owning fragment of a string (usually owned by the context). This is a
relatively simple class that is defined in LLVM. Provide a simple wrapper in
the MLIR C API that contains the pointer and length of the string fragment and
use it for Standard attribute functions that return StringRef instead of the
previous, callback-based mechanism.

Sean Silva 84a6da67e6 [mlir] Fix some edge cases around 0-element TensorFromElementsOp
This introduces a builder for the more general case that supports zero
elements (where the element type can't be inferred from the ValueRange,
since it might be empty).

Also, fix up some cases in ShapeToStandard lowering that hit this. It
happens very easily when dealing with shapes of 0-D tensors.

The SameOperandsAndResultElementType is redundant with the new
