9c0bce7e - [MLIR][Transform] Fix crash in CheckUses when op lacks MemoryEffectOpInterface (#188998)

[MLIR][Transform] Fix crash in CheckUses when op lacks MemoryEffectOpInterface (#188998) collectFreedValues used cast<MemoryEffectOpInterface> unconditionally on every op encountered during the walk. Ops that do not implement the interface (e.g. pdl.pattern, pdl.operands, pdl.types inside a transform.with_pdl_patterns region) trigger the cast assertion, crashing mlir-opt when -transform-dialect-check-uses is requested. Change the cast to dyn_cast and skip ops that don't implement the interface; they cannot free transform values and are safely ignored. Fixes #120944 Assisted-by: Claude Code
