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.) llvm-svn: 226866 2015-01-22 22:36:45 +01:00			`; RUN: not llvm-as < %s -disable-output 2>&1 \| FileCheck %s`

AsmParser: Don't crash on unresolved !tbaa Instead of crashing, give a nice error. As a drive-by, fix the location associated with the errors for unresolved metadata (the location was off by one token). llvm-svn: 265507 2016-04-06 04:06:40 +02:00			`; CHECK: [[@LINE+1]]:13: error: use of undefined metadata '!1'`
