Jeff Niu 58a47508f0 (Reland) [mlir] Switch segment size attributes to DenseI32ArrayAttr
This reland includes changes to the Python bindings.

Switch variadic operand and result segment size attributes to use the
dense i32 array. Dense integer arrays were introduced primarily to
represent index lists. They are a better fit for segment sizes than
dense elements attrs.

Depends on D131801

Ingo Müller d4a7ca81fe [mlir][doc] Fix usage of PatternApplicator.
The constructor of PatternApplicator doesn't have a constructor that
accepts only a `RewritePatternSet` as currently used in the example
code in PatternRewriter.md. Instead, one has to turn it into a
`FrozenRewritePatternSet`.

River Riddle 6edef13569 [mlir:PassOption] Rework ListOption parsing and add support for std::vector/SmallVector options
ListOption currently uses llvm:🆑:list under the hood, but the usages
of ListOption are generally a tad different from llvm:🆑:list. This
commit codifies this by making ListOption implicitly comma separated,
and removes the explicit flag set for all of the current list options.
The new parsing for comma separation of ListOption also adds in support
for skipping over delimited sub-ranges (i.e. {}, [], (), "", ''). This
more easily supports nested options that use those as part of the
format, and this constraint (balanced delimiters) is already codified
in the syntax of pass pipelines.

This dialect is intended to model lower level/branch based control-flow constructs. The initial set

River Riddle 0289a2692e [mlir] Add support for filtering patterns based on debug names and labels
This revision allows for attaching "debug labels" to patterns, and provides to FrozenRewritePatternSet for  filtering patterns based on these labels (in addition to the debug name of the pattern). This will greatly simplify the ability to write tests targeted towards specific patterns (in cases where many patterns may interact),  will also simplify debugging pattern application by observing how application changes when enabling/disabling specific patterns.

To enable better reuse of pattern rewrite options between passes, this revision also adds a new PassUtil.td file to the Rewrite/ library that will allow for passes to easily hook into a common interface for pattern debugging. Two options are used to seed this utility, `disable-patterns` and `enable-patterns`, which are used to enable the filtering behavior indicated above.

This is the fourth and final patch in a series of patches fixing markdown links and references inside the mlir documentation. This patch combined with the other three should fix almost every broken link on mlir.llvm.org as far as I can tell.

This patch in particular addresses all Markdown files in the top level docs directory.

River Riddle 2257e4a70e [mlir] Allow derived rewrite patterns to define a non-virtual `initialize` hook
This is a hook that allows for providing custom initialization of the pattern, e.g. if it has bounded recursion, setting the debug name, etc., without needing to define a custom constructor. A non-virtual hook was chosen to avoid polluting the vtable with code that we really just want to be inlined when constructing the pattern. The alternative to this would be to just define a constructor for each pattern, this unfortunately creates a lot of otherwise unnecessary boiler plate for a lot of patterns and a hook provides a much simpler/cleaner interface for the very common case.

River Riddle b99bd77162 [mlir][Pattern] Refactor the Pattern class into a "metadata only" class
The Pattern class was originally intended to be used for solely matching operations, but that use never materialized. All of the pattern infrastructure uses RewritePattern, and the infrastructure for pure matching(Matchers.h) is implemented inline. This means that this class isn't a useful abstraction at the moment, so this revision refactors it to solely encapsulate the "metadata" of a pattern. The metadata includes the various state describing a pattern; benefit, root operation, etc. The API on PatternApplicator is updated to now operate on `Pattern`s as nothing special from `RewritePattern` is necessary.

This refactoring is also necessary for the upcoming use of PDL patterns alongside C++ rewrite patterns.
