Clean up the last remaining misanalyzed procedure boundaries After spending a few hours on correctly decompiling ZUN's bulky custom text renderer used in TH02 and TH03, it unfortunately turned out that TLINK doesn't actually give us the fine-grained control over segment ordering we'd like to have in a project like this, and that we can't slot code from one object file in between segments from another object file. This means that yes, we really have to decompile the functions in the order they appear in the executables, starting on either end. So, have a boring janitorial commit instead.
