<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-mlir Author: Matthias Springer (matthias-springer) <details> <summary>Changes</summary> A type conversion rule cannot make any assumptions about the number of pre-existing types in the `results` vector. This commit fixes a failed assertion in a SparseTensor type conversion rule. This is only reproducible when type conversion caching is deactivated. There's no way to do this at the moment. This commit is in preparation of adding context-aware type conversions, which will deactivate type caching in such cases.
