ad0c69ea29 Make these definitions safe again. 
As of this moment, the performance win on new-metrics.rkt for
using the unsafe version is about 1% (avg over 10 runs), which
isn't enough to make it worth the segfaults. I believe that
changes to the JIT since 2012 (when the unsafe ops were added)
have sped up struct access.
