Contains test changes from https://github.com/llvm/llvm-project/pull/81677 that are simple test changes. For the most part just makes the tests allow more flexibility in the callstacks produced by asan. Note: this PR has the exact changes from https://github.com/llvm/llvm-project/pull/81677 in addition to a revert commit to remove the ones that require other things from that PR. This will be squashed, ofc. I just left things unsquashed for reviewing pleasure :). This is a non-functional-change
