In a crash recovery we already have all the tablespace objects created.
This function compares the space id information in the InnoDB data dictionary

In a normal startup, we create the tablespace objects for every table in
InnoDB's data dictionary, if the corresponding .ibd file exists.
We also scan the biggest space id, and store it to fil_system. */
