  to b6c33dc967a55fe023aee174a9f3d6cd3a340943
  - Merge "Move native coverage output directory." into main
  - Move native coverage output directory.
    
    Native coverage will be written to /data/local/tmp instead of
    /data/misc/trace, allowing coverage tests to run on non-coverage builds.
    
    Test: atest libunwindstack_unit_test --experimental-coverage
    Test: m droid && acloud create --local-image
