backend: Remove argID in function arguments iteration

argID is used for checking whether the argument has a byvalue attribute,
and now llvm can do this with the hasByValueAttr function of the
argument, so there is no need to use the old api.

remove all Makefiles

There are two motivations for this change:

 - As we're using CMake, we don't need to maintain another build system. More
   code is more burden.
 - We want to delete `ocl_stdlib_str.cpp` completely as it can be
   auto-generated from `ocl_stdlib.h`. But in the current Makefile build system,
   we used it directly in `all_in_one` directory. So the removal of Makefile
   would help us on this.
