Reid Kleckner 4c27f8d49e Reland r229944: EH: Prune unreachable resume instructions during Dwarf EH preparation
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.
