Description

The code for freeing memory in MemArena doesn't free all memory on 64-bit. (The amount leaked is about 32MB for a GC game or 96MB for a Wii game.) In addition, this code is a pain to work with. I rewrote this part of the code. Patch is attached.

One problem with the current code is that it tries to duplicate the same conditional logic in 3 different places but written in 3 different ways which easily leads to bugs like these. Actually the code for freeing memory doesn't need to know if we're emulating GC or Wii on 32-bit or 64-bit. It doesn't need to assume relationship between certain fields in the table where the addresses are stored. The goal is to free each unique non-null address once.
