-Turning off nullable inlining since it caused a performance regression here:
-crbug.com/965189. If R8 ever mitigates this, we can re-enable this.
-
 Turning off outlining because it caused issues when synchronized proguarding
 Trichrome due to illegal dex references (crbug.com/956839). Will only be used
 for android_apk() targets that set `disable_r8_outlining = true`):
