remove -rec flag from atdgen

Summary: public
Remove spurious recursion between type and function declarations in the files
generated via `atdgen`. This speeds up the compilation time of `make clang` by
almost half (one-shot measurements: 59s -> 36s).

Silence warning 39 on this generated code to make compilation pass.
