Comment(by simonmar):

 Sadly the situation with Cost Centre Stacks is that it's still work in
 progress and I didn't manage to document it (beyond comments in the code)
 before I left MSR.

 Simon is right that you can't statically determine which CCS a particular
 allocation will be attributed to.  However, if the `let` is within the
 scope of a particular SCC, then the allocation should be attributed to
 Cost Centre Stacks that have that SCC label on the top.  There might be
 many such stacks in the profile, if the current function was called from
 multiple different places.
