Use `wp_installing()` instead of `WP_INSTALLING` constant. The `WP_INSTALLING` constant is a flag that WordPress sets in a number of places, telling the system that options should be fetched directly from the database instead of from the cache, that WP should not ping wordpress.org for updates, that the normal "not installed" checks should be bypassed, and so on. A constant is generally necessary for this purpose, because the flag is typically set before the WP bootstrap, meaning that WP functions are not yet available. However, it is possible - notably, during `wpmu_create_blog()` - for the "installing" flag to be set after WP has already loaded. In these cases, `WP_INSTALLING` would be set for the remainder of the process, since there's no way to change a constant once it's defined. This, in turn, polluted later function calls that ought to have been outside the scope of site creation, particularly the non-caching of option data. The problem was particularly evident in the case of the automated tests, where `WP_INSTALLING` was set the first time a site was created, and remained set for the rest of the suite. The new `wp_installing()` function allows developers to fetch the current installation status (when called without any arguments) or to set the installation status (when called with a boolean `true` or `false`). Use of the `WP_INSTALLING` constant is still supported; `wp_installing()` will default to `true` if the constant is defined during the bootstrap. Props boonebgorges, jeremyfelt. See #31130.
