Revert the fix for incorrect package-private overriding.

Revert the fix for incorrect package-private overriding.

This fixes FIFA 2012, the download portion of which relies on the
old bug, without breaking instrumentation tests. The problem is that
dexopt tries to quicken method calls, and gets confused by this case
where the apparent static method resolution differs from the actual
one at runtime, depending on the targetSdkVersion of the specific app.
dexopt can't make an ahead-of-time decision in a world where the rules
might change at runtime.
