Systems Testing With VTS

New Dalvik Bytecodes and Formats
Dalvik now offers new bytecode formats 45cc and 4rcc and placeholder opcodes for invoke-polymorphic and invoke-polymorphic/range, which are the first dex instructions that use these new formats. In addition to a method_idx that gives the invoked method, these instructions also provide a proto_idx that gives the (static) type signature of the call site.
