Fix the legacy version of `GetDexOptNeeded`.
- when `profile_changed` is true but the target compiler filter is worse
than the current:
- Before: returns kDex2OatForFilter
- After: returns kNoDexOptNeeded
- when `downgrade` is true but there is no usable odex/vdex files:
- Before: returns kDex2OatFromScratch
- After: return kNoDexOptNeeded
- when `profile_changed` and `downgrade` are both true:
- Before: kDex2OatForFilter
- After: the same as `profile_changed` is false and `downgrade` is
true.
- when the usable vdex file is in the DM file:
- Before: returns kDex2OatForFilter with an arbitrary sign
- After: returns kDex2OatFromScratch
