Cache @ContentView annotation lookups for activities
Caching the annotation look up so the reflection cost only
needs to be paid once.
This provides a performance benefit.
Test: tested with local activity unit tests

This has been fixed internally and will be available in Fragment 1.1.0-alpha05
Description
Version used: 1.0.0-alpha04, 1.1.0-alpha04, respectively
As the @ContentView annotation lookup is done at runtime, it would be a performance benefit to cache the annotation lookup so that you only need to pay the reflection cost once.
This is particularly important for Fragments where onCreateView() can run multiple times (i.e., when coming back from the back stack).
