Use direct class pointers at allocation sites in the compiled code.
- Rather than looking up a class from its type ID (and checking if
it's resolved/initialized, resolving/initializing if not), use
direct class pointers, if possible (boot-code-to-boot-class pointers
and app-code-to-boot-class pointers.)
- This results in a 1-2% speedup in Ritz MemAllocTest on Nexus 4.
- Embedding the object size (along with class pointers) caused a 1-2%
slowdown in MemAllocTest and isn't implemented in this change.
- TODO: do the same for array allocations.
- TODO: when/if an application gets its own image, implement
app-code-to-app-class pointers.
- Fix a -XX:gc bug.

- Add /tmp/android-data/dalvik-cache to the list of locations to
remove oat files in clean-oat-host.

- Add back a dropped UNLIKELY in FindMethodFromCode().
