Optimizing: Treat app image objects as non-movable.

Treat app image objects similar to boot image objects and
avoid unnecessary read barriers for app image `HLoadClass`
and `HInstanceOf` checks with app image `HLoadClass` input.

Extend other optimizations to treat app image classes the
same way as boot image classes even though this remains
mostly dormant because we currently do not initialize app
image classes with class initializers; the experimental
flag `--initialize-app-image-classes` is false by default.

Test: m test-art-host-gtest
Test: testrunner.py --host --optimizing --speed-profile
