Extended Description

Sometime between ROUGHLY 2009-09-08 (Build #16387) and
2009-10-16 (Build #16482), the instruction counts for 
the sac/apex/buildv/buildv.sac benchmark doubled.
When I find some spare time to go rebuilding old compiler
versions, I'll go find out what happened.
BTW: It would be nice if we had a simple (i.e., always there)
mechanism to leave old copies of the compiler and stdlib 
in a usable form on our machines. That would make this
sort of investigation trivial.
