[Sanitizer] Fix failing sanitizer tests

[Sanitizer] Fix failing sanitizer tests

The new pass manager was enabled by default [1].

The commit message states the following relevant differences:
  * The inliner works slightly differently
  * -O1 does some amount of inlining

These tests are affected because they specify `-O1` and then check the
reported stack trace.
