Mats Petersson 3f00e10bdd [mlir][OpenMP]Support for modifiers in workshare loops
Pass the modifiers from the Flang parser to FIR/MLIR workshare
loop operation.

Not yet supporting the SIMD modifier, which is a bit more work
than just adding it to the list of modifiers, so will go in a
separate patch.

This adds a new field to the WsLoopOp.

Also add test for dynamic WSLoop, checking that dynamic schedule calls
the init and next functions as expected.

Matthias Springer 3bbc869e2e [mlir][linalg][bufferize] Support scf::IfOp
This commit adds support for scf::IfOp to comprehensive bufferization. Support is currently limited to cases where both branches yield tensors that bufferize to the same buffer.

To keep the analysis simple, scf::IfOp are treated as memory writes for analysis purposes, even if no op inside any branch is writing. (scf::ForOps are handled in the same way.)

Aart Bik bd5494d127 [mlir][sparse] make index type explicit in public API of support library
The current implementation used explicit index->int64_t casts for some, but
not all instances of passing values of type "index" in and from the sparse
support library. This revision makes the situation more consistent by
using new "index_t" type at all such places  (which allows for less trivial
casting in the generated MLIR code).  Note that the current revision still
assumes that "index" is 64-bit wide. If we want to support targets with
alternative "index" bit widths, we need to build the support library different.
But the current revision is a step forward by making this requirement explicit
and more visible.

Shraiysh Vaishay c4c7e06bd7 [MLIR][OpenMP] Shifted hint from CriticalOp to CriticalDeclareOp
According to the OpenMP 5.0 standard, names and hints of critical operation are
closely related. The following are the restrictions on them:
 - Unless the effect is as if `hint(omp_sync_hint_none)` was specified, the
   critical construct must specify a name.
 - If the hint clause is specified, each of the critical constructs with the
   same name must have a hint clause for which the hint-expression evaluates to
   the same value.

These restrictions will be enforced by design if the hint expression is a part
of the `omp.critical.declare` operation.
 - Any operation with no "name" will be considered to have
   `hint(omp_sync_hint_none)`.
 - All the operations with the same "name" will have the same hint value.

Nicolas Vasilache 6bb7d2474f [mlir][Linalg] Add a first vectorization pattern for conv1d in NWCxWCF format.
This revision uses the newly refactored StructuredGenerator to create a simple vectorization for conv1d_nwc_wcf.

Note that the pattern is not specific to the op and is technically not even specific to the ConvolutionOpInterface (modulo minor details related to dilations and strides).

The overall design follows the same ideas as the lowering of vector::ContractionOp -> vector::OuterProduct: it seeks to be minimally complex, composable and extensible while avoiding inference analysis. Instead, we metaprogram the maps/indexings we expect and we match against them.

This is just a first stab and still needs to be evaluated for performance.
Other tradeoffs are possible that should be explored.

Vladislav Vinogradov e41ebbecf9 [mlir][RFC] Refactor layout representation in MemRefType
The change is based on the proposal from the following discussion:
https://llvm.discourse.group/t/rfc-memreftype-affine-maps-list-vs-single-item/3968

* Introduce `MemRefLayoutAttr` interface to get `AffineMap` from an `Attribute`
  (`AffineMapAttr` implements this interface).
* Store layout as a single generic `MemRefLayoutAttr`.

This change removes the affine map composition feature and related API.
Actually, while the `MemRefType` itself supported it, almost none of the upstream
can work with more than 1 affine map in `MemRefType`.

The introduced `MemRefLayoutAttr` allows to re-implement this feature
in a more stable way - via separate attribute class.

Also the interface allows to use different layout representations rather than affine maps.
For example, the described "stride + offset" form, which is currently supported in ASM parser only,
can now be expressed as separate attribute.
