Use instruction specific dalvik cache dirs.

- All oat & art files are now placed under /data/dalvik-cache/<isa>/.
- GetDalvikCacheOrDie now requires a mandatory subdirectory argument,
  and is implicitly rooted under /data/.
- Added helper methods to convert InstructionSet enums into strings
  and vice versa.
