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.
