Closes#2167
Based off sub_71001D16A0 with shortcut modifications:
* code marks new entries for evolution processing later using the low
bit (hence the << 1); in save files I can't see any bits set, but I
can't see anywhere in the code that DOESNT set this bit. Thus the
assumption of post-processing.
As noted in gameplay, a new capture doesn't set Min and Max; it only
sets it if it is above the usual sizing values.
Megas apparently don't set until seen in battle, so don't worry about
setting the other forme based indexes.
