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.
