This revision fixes the import of LLVM IR to handle debug metadata with cyclic dependencies. It deletes the elements list of the composite type if a cyclic dependency is detected. The revision is meant as a band aid to avoid infinite recursion during the import of cyclic debug metadata. Long term solutions are currently discussed here: https://discourse.llvm.org/t/handling-cyclic-dependencies-in-debug-info/67526/4 Reviewed By: Dinistro Differential Revision: https://reviews.llvm.org/D142086
