Well, I was lazy when I did this and it was done in two stages.  Stage
1:  Remove uses of alloc_16_to_eax and friends and do a full build. 
Stage 2: Remove the actual code for alloc_16_to_eax and friends and use
stage 1 to do a full build.  These two stages were done in the
snapshots.  Looks like stage 1 was done in the 2012-01 snapshot and
stage 2 in 2012-02.
