Oat compiler integration snapshot.
Cleanly compiles, but not integrated. Old-world dependencies captured
in hacked-up temporary files "Dalvik.h" and "HackStubs.cc".
Dalvik.h is a placeholder that captures all of the constants, struct
definitions and inline functions the compiler needs. It largely consists
of declaration fragments of libdex, Object.h, DvmDex.h and Thread.h.
HackStubs.cc contains empty shells for some required libdex routines.
