Reduce AOT initialization.
When compiling apps there is no need to resolve all types in the dex file, just
those declared in the dex file. There's also no need to initialize static
fields if we can only leave the class in a verified state.
Increase use of CompilerDriver::IsImage.
Move timing of dex2oat setup to before Runtime::Create.
On run-test 056 the performance improvement is an order of magnitude, for
ThinkFree dex2oat time is dominated by compilation and this change has no
effect.
Bug 10316099.
