[asan] don't unpoison redzones on function exit in use-after-return mode.
Summary:
Before this change the instrumented code before Ret instructions looked like:
<Unpoison Frame Redzones>
if (Frame != OriginalFrame) // I.e. Frame is fake
<Poison Complete Frame>
Now the instrumented code looks like:
if (Frame != OriginalFrame) // I.e. Frame is fake
<Poison Complete Frame>
else
<Unpoison Frame Redzones>
