Redundant tree inliner code?

[Ziemowit Laski]

A recursive grep for deferred_fns (which I believe came in with the new
tree inlining recently) shows that the variable is defined in three
different places.  Is there a reason for this, or could it just go
into c-common.[ch]?

We stumbled across this while working on our persistent front-end, and
the current "distribution" of deferred_fns makes life extra hellish
for us. :)
