IR: Update references to temporaries before deleting During `MDNode::deleteTemporary()`, call `replaceAllUsesWith(nullptr)` to update all tracking references to `nullptr`. This fixes PR22280, where inverted destruction order between tracking references and the temporaries themselves caused a use-after-free in `LLParser`. An alternative fix would be to add an assertion that there are no users, and continue to fix inverted destruction order in clients (like `LLParser`), but instead I decided to make getting-teardown-right easy. (If someone disagrees let me know.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@226866 91177308-0d34-0410-b5e6-96231b3b80d8 2015-01-22 21:36:45 +00:00			`; RUN: not llvm-as < %s -disable-output 2>&1 \| FileCheck %s`
