New description:

 Ticky-ticky profiling has bitrotted in 6.4, after the rewrite of the code
 generator.  Much of the code survived the transition, but it hasn't been
 tested and no doubt some work is required to get it going again.

Comment:

 Tim: a very basic version of ticky-ticky profiling (specifically: entry
 counts, allocations) now works again (partly due to your work) but it's
 very partial.  Norman and I are up-heaving the code generator at the
 moment, so don't worry about fixing this for now.  In a few months time,
 it'd be great to make ticky-ticky work properly again.

 Meanwhile I'm milestoning it "bottom" because I doubt we'll do this
 ourselves unless we need it for some reason.

 Thanks.

 Simon
