Fix the double-deletion of AnalysisResolver when delegating through to Dwarf EH preparation by creating one from scratch. Hopefully the new pass manager simplifies this. This reverts commit r229952. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@231719 91177308-0d34-0410-b5e6-96231b3b80d8
