- Be a little more lenient when reading the cies/fdes. If next entry data winds up incorrect, don't fail, simply stop processing the entries. This only applies when reading all of the cies/fdes at once. - Fail to init an eh_frame with no entries and fallback to assuming the eh_frame has no header instead. - Change the step to always try debug_frame first which has the most accurate information. - Add small unit tests and a couple of offline unit tests to verify this behavior. These changes are needed to support offline unwinding since it depends on this new behavior. Bug: 65682279 Test: Ran new unit tests. Change-Id: I3529f1b0c8e14cd7409494e5de2f3c9e78d0855e
