Title: faster NA, NaN handling

Travis build seems to have failed for unrelated reasons.

There are probably better names than `Rcpp_IsNA` and `Rcpp_IsNaN`, though. Maybe just `is_na` and `is_nan`?

I would place `Rcpp_IsNA` / `Rcpp_IsNaN` inline in `is_na.h` but I imagine they might be useful elsewhere too.
