Optimize creation of bindings for @Inject classes by memoizing Constructors for classes with generated $$AtInject adapters and factories for classes without generated $$AtInject adapters.

Also considered generating factories as part of $$AtInject adapters, but that was potentially bad for android, where increasing the number of classes/methods is a concern.

For [], this CL brings down the CPU cost of FailoverLoader.getAtInjectBinding() in []prof testing from 1.3% of the total [] CPU cost to 0.53% (generating factories would bring it down to 0.27%).

Create a temporary reflective loader for Dagger 1.0 clients that MUST use proguard for obfuscation, before we are ready to migrate to 2.0.  This creates a reflective module adapter and a loader which doesn't even try to load the generated adapters, permitting obfuscated provision and injection points to be inferred from the new class names at runtime, and therefore match and succeed in wiring.
