This patch adds `getLoopInductionVars`, `getLoopLowerBounds`,
`getLoopBounds`, `getLoopSteps` interface methods to
`LoopLIkeOpInterface`. The corresponding single value versions have been
moved to shared class declaration and have been implemented based on the
new interface methods.
This PR extracts the existing `scf.forall` to `scf.for` conversion logic
inside a transform op (https://github.com/llvm/llvm-project/pull/65474)
into a standalone function which can be used in other transformations
and adds a `scf-forall-to-for` pass.
