[flang] Fix some memory leaks #121050

matthias-springer · 2024-12-24T12:09:02Z

This commit fixes some but not all memory leaks in Flang. There are still 91 tests that fail with ASAN.

Use mlir::OwningOpRef instead of std::unique_ptr. The latter does not free allocations of nested blocks.
Pass ModuleOp as value instead of reference.
Add few missing deallocations in test cases and other places.
