In order to filter out file names based on the user's settings, QFileSystemModel used to have a loop that tested if a given file name matched one of the filters. The problem is that each filter (a wildcard) was converted to a QRegularExpression _inside_ the loop. This causes a quadratic behavior (number of files * number of filters). Instead, build the regexps once when the filters are set (or the case sensitivity is changed, as that affects the filtering), and simply _use_ them in the loop. Simplify and correct some related code as a drive by.
