beam_validator: Add is_bitstring/1 as a safe BIF
beam_validator wrongly complained that the following was not safe because it didn't know that is_bitstring/1 is safe: food(Curriculum) -> [try is_bitstring(functions) catch _ -> 0 end, Curriculum]. While we are it, also add a new bif_SUITE test suite to cover some more code in beam_validator.
