  -----------
  Reapply "[DebugInfo] Make DIArgList inherit from Metadata and always unique"

This reverts commit 0fd5dc94380d5fe666dc6c603b4bb782cef743e7.

The original commit removed DIArgLists from being in an MDNode map, but did
not insert a new `delete` in the LLVMContextImpl destructor. This
reapply adds that call to delete, preventing a memory leak.
