[Bug c++/22635] New: OVERLOAD should not be a linked list of trees

[pinskia at gcc dot gnu dot org]

I noticed this when looking at compile time / memory usage of PR 8361 and I noticed that OVERLOAD is 
currently a link list and we only use about 2 of the fields in the tree which seems like a waste for a full 
tree.  I started to change it to be a VEC but ran into problems as it looks like we can be in the middle of 
the linked list but I did not check for sure.
