Recent work has introduced support for constructing loops via `::build` with
callbacks that construct loop bodies using only the core OpBuilder. This is now
supported on all loop types that Linalg lowers to. Refactor LoopNestBuilder in
Linalg to rely on this functionality instead of using a custom EDSC-based
approach to creating loop nests.
The specialization targeting parallel loops is also simplified by factoring out
the recursive call into a separate static function and considering only two
alternatives: top-level loop is parallel or sequential.
This removes the last remaining in-tree use of edsc::LoopBuilder, which is now
deprecated and will be removed soon.
Differential Revision: https://reviews.llvm.org/D81873
Similarly to `scf::ForOp`, introduce additional `function_ref` arguments to
`::build` functions of SCF `ParallelOp` and `ReduceOp`. The provided functions
will be called to construct the body of the respective operations while
constructing the operation itself. Exercise them in LoopUtils.

Summary:
This revision replaces MatmulOp, now that DRR rules have been dropped.
This revision also fixes minor parsing bugs and a plugs a few holes to get e2e paths working (e.g. library call emission).
During the replacement the i32 version had to be dropped because only the EDSC operators +, *, etc support type inference.
Deciding on a type-polymorphic behavior, and implementing it, is left for future work.

Summary: FileLineColLoc allows the column and line to be zero to represent unknown column and/or unknown line/column information. However, SourceMgr::FindLocForLineAndColumn treats line 0 and col 0 valid and pointing to the first line and col, respectively. To adapt this mismatch in semantics, we explicitly check line/col being zeros in SourceMgrDiagnosticHandler::convertLocToSMLoc

It is quite common for the same type to be converted many types throughout the conversion process, and there isn't any good reason why we aren't caching that result. Especially given that we currently use identity conversion to signify legality. This revision also adds a few additional helpers to TypeConverter.

This is intended to avoid programming mistake where a temporary OpOperand is
created, for example:
for (OpOperand user : result.getUsers()) {
It can be confusing for the user, in particular since in MLIR most classes are intended to
be copied around by value while they have reference semantics.

******************** TEST 'MLIR :: Examples/standalone/test.toy' FAILED ********************

Summary:
This CL introduces an integration test directory for MLIR in general, with
vector dialect integration tests in particular as a first working suite. To
run all the integration tests (and currently just the vector suite):
$ cmake --build . --target check-mlir-integration
[0/1] Running the MLIR integration tests
Testing Time: 0.24s
Passed: 22
The general call is to contribute to this integration test directory with more
tests and other suites, running end-to-end examples that may be too heavy for
the regular test directory, but should be tested occasionally to verify the
health of MLIR.

Add a pattern for expanding tanh op into exp form.
A `tanh` is expanded into:
1) 1-exp^{-2x} / 1+exp^{-2x}, if x => 0
2) exp^{2x}-1 / exp^{2x}+1 , if x < 0.

Similarly to `scf::ForOp`, introduce additional `function_ref` arguments to
`AffineForOp::build` that can be used to populate the body of the loop during
its construction. Provide compatibility functions for constructing affine loop
nests using `edsc::ScopedContext`.
`edsc::AffineLoopNestBuilder` and reletad functionality is now deprecated and
will be removed soon, users are expected to switch to `affineLoopNestBuilder`
that provides similar functionality with a simpler OpBuilder-based
implementation.

In the affine symbol and dimension check, the code currently assumes
`getAffineScope` and its users `isValidDim` and `isValidSymbol` are only called
on values defined in regions that have a parent Op with `AffineScope` trait.
This is not necessarily the case, and these functions may be called on valid IR
that does not satisfy this assumption. Return `nullptr` from `getAffineScope`
if there is no parent op with `AffineScope` trait. Treat this case
conservatively in `isValidSymbol` by only accepting as symbols the values that
are guaranteed to be symbols (constants, and certain operations). No
modifications are necessary to `isValidDim` that delegates most of the work to
`isValidDim`.

allocations cannot be moved freely and can remain in divergent control flow.
The current BufferPlacement pass does not support allocation nodes that carry
additional dependencies (like in the case of dynamic shaped types). These
allocations can often not be moved freely and in turn might remain in divergent
control-flow branches. This requires a different strategy with respect to block
arguments and aliases. This CL adds additinal functionality to support
allocation nodes in divergent control flow while avoiding memory leaks.

This patch has shift ops conversion implementation. In SPIR-V dialect,
`Shift` and `Base` may have different bit width. On the contrary,
in LLVM dialect both `Base` and `Shift` have to be of the same bit width.
This leads to the following cases:
- if `Base` has the same bit width as `Shift`, the conversion is
straightforward.
- if `Base` has a greater bit width than `Shift`, shift is sign/zero
extended first. Then the extended value is passed to the shift.
- otherwise the conversion is considered to be illegal.

Modify structure type in SPIR-V dialect to support:
1) Multiple decorations per structure member
2) Key-value based decorations (e.g., MatrixStride)
This commit kept the Offset decoration separate from members'
decorations container for easier implementation and logical clarity.
As such, all references to Structure layoutinfo are now offsetinfo,
and any member layout defining decoration (e.g., RowMajor for Matrix)
will be add to the members' decorations container along with its
value if any.

Add Adaptor alias alongside OperandAdaptor to make next renaming more
