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
