This fixes the issue exposed in PR31393, where we weren't trying sufficiently hard to diagnose bad TBAA metadata. This does reduce the variety in the error messages we print out, but I think the tradeoff of verifying more, simply and quickly overrules the need for more helpful error messags here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@290713 91177308-0d34-0410-b5e6-96231b3b80d8
