[Vm-dev] Aarch64 compare bug

[ken.dickey at whidbey.com]

Had a chance to play a bit last night.

Stepping through
   Integer readFrom: (ReadStream on: '8000000000000000') base:16.
tells the tale.

Definitely an edge problem going from SmallInteger into bignums.

I'll try to get into why in the next couple of days.
