Adrian Kuegel 2219f9f57c [mlir][MemRef] Fix MemRefCopyOpLowering to use correct number of bytes
When lowering to memrefCopy call, the size for i1 type was calculated as 0.
Instead of using getTypeSizeInBits() and dividing by 8, we should just use getTypeSize().

Adrian Kuegel 5b02a48085 [mlir][MemRef] Fix MemRefCastOpLowering for 32 bit index type.
The lowering creates llvm.insertvalue with the rank value, so it needs to use
index type instead of 64 bit integer type. Otherwise, we get an error:

llvm.insertvalue' op Type mismatch: cannot insert 'i64' into '!llvm.struct<(i32, ptr<i8>)>'

gysit a3655de2c8 [mlir][OpDSL] Add support for basic rank polymorphism.
Previously, OpDSL did not support rank polymorphism, which required a separate implementation of linalg.fill. This revision extends OpDSL to support rank polymorphism for a limited class of operations that access only scalars and tensors of rank zero. At operation instantiation time, it scales these scalar computations to multi-dimensional pointwise computations by replacing the empty indexing maps with identity index maps. The revision does not change the DSL itself, instead it adapts the Python emitter and the YAML generator to generate different indexing maps and and iterators depending on the rank of the first output.

Additionally, the revision introduces a `linalg.fill_tensor` operation that in a future revision shall replace the current handwritten `linalg.fill` operation. `linalg.fill_tensor` is thus only temporarily available and will be renamed to `linalg.fill`.

Thomas Raoux 5ab04bc068 [mlir][gpu] Add device side async copy operations
Add new operations to the gpu dialect to represent device side
asynchronous copies. This also add the lowering of those operations to
nvvm dialect.
Those ops are meant to be low level and map directly to llvm dialects
like nvvm or rocdl.

We can further add higher level of abstraction by building on top of
those operations.

River Riddle faf42264e5 [PDLL] Add support for user defined constraint and rewrite functions
These functions allow for defining pattern fragments usable within the `match` and `rewrite` sections of a pattern. The main structure of Constraints and Rewrites functions are the same, and are similar to functions in other languages; they contain a signature (i.e. name, argument list, result list) and a body:

```pdll
// Constraint that takes a value as an input, and produces a value:
Constraint Cst(arg: Value) -> Value { ... }

// Constraint that returns multiple values:
Constraint Cst() -> (result1: Value, result2: ValueRange);
```

When returning multiple results, each result can be optionally be named (the result of a Constraint/Rewrite in the case of multiple results is a tuple).

These body of a Constraint/Rewrite functions can be specified in several ways:

* Externally
In this case we are importing an external function (registered by the user outside of PDLL):

```pdll
Constraint Foo(op: Op);
Rewrite Bar();
```

* In PDLL (using PDLL constructs)
In this case, the body is defined using PDLL constructs:

```pdll
Rewrite BuildFooOp() {
  // The result type of the Rewrite is inferred from the return.
  return op<my_dialect.foo>;
}
// Constraints/Rewrites can also implement a lambda/expression
// body for simple one line bodies.
Rewrite BuildFooOp() => op<my_dialect.foo>;
```

* In PDLL (using a native/C++ code block)
In this case the body is specified using a C++(or potentially other language at some point) code block. When building PDLL in AOT mode this will generate a native constraint/rewrite and register it with the PDL bytecode.

```pdll
Rewrite BuildFooOp() -> Op<my_dialect.foo> [{
  return rewriter.create<my_dialect::FooOp>(...);
}];
```

Reuse the higher precision F32 approximation for the F16 one (by expanding and

(e.g., these are only for F32 and should not be expanded, that reusing
higher-precision ones for lower precision is undesirable due to increased
compute cost and only approximations per exact type is preferred, or this is
appropriate [at least as fallback] but we need to see how to make it more

River Riddle d7f0083dca [mlir:ODS] Deprecate Op parser/printer fields in favor of a new hasCustomAssemblyFormat field
Currently if an operation wants a C++ implemented parser/printer, it specifies inline
code blocks. This is quite problematic for various reasons, e.g. it requires defining
C++ inside of Tablegen which is discouraged when possible, but mainly because
nearly all usages simply forward to static functions (e.g. `static void parseSomeOp(...)`)
with users devising their own standards for how these are defined.

This commit adds support for a `hasCustomAssemblyFormat` bit field that specifies if
a C++ parser/printer is needed, and when set to 1 declares the parse/print methods for
operations to override. For migration purposes, the existing behavior is untouched. Upstream
usages will be replaced in a followup to keep this patch focused on the new implementation.
