1. <iterator>: reduced parsing time …

   * Replaced `<istream>` include with `<iosfwd>` because `[io]stream_iterator`
     needs only `basic_[io]stream` forward declaration.
   * Moved `[io]streambuf_iterator` iterator definition to `<iterator>` because
     their definition has to come when `<iterator>` is included.
   * Include `<iterator>` in `<xlocmon>`, `<xlocnum>`, and `<xloctime>` as
     the `[io]streambuf_iterator` definition are required there, and `<xutility>`
     already included via other includes.
   
   Parsing times:
   
   | header     |          clang          |           msvc          |
   |------------|-------------------------|-------------------------|
   | <iterator> | 0.371 -> 0.163 (-56.1%) | 0.216 -> 0.094 (-56.5%) |
   | <istream>  | 0.366 -> 0.372 ( +1.6%) | 0.215 -> 0.216 ( +0.5%) |
   | <xlocmon>  | 0.358 -> 0.364 ( +1.7%) | 0.211 -> 0.211 (    0%) |
   | <xlocnum>  | 0.357 -> 0.360 ( +0.8%) | 0.207 -> 0.208 ( +0.5%) |
   | <xloctime> | 0.364 -> 0.370 ( +1.6%) | 0.211 -> 0.214 ( +1.4%) |
