Use ELF function index to distinguish generated functions.

We replaced LLVMLongName and LLVMStubName with ElfFuncName,
and we are using the simple name: Art0, Art1, ..., ArtN,
as the function name of every generated functions.  This
gives us 3 benefits:

1. We can avoid the ambiguous function name returned by
   LLVMLongName() in some special situation.

2. We don't need to have the art::Method object during
   the executable linking procedure.  Besides, this will
   make bootstrapping easier.

3. Reduce the size of the ELF executable, since we don't
   have to save a long function name, which usually contains
   more than 30 characters.
