This is sort-of a spin-off from effective_target_tail_call: I thought
that'd best be implemented by scanning a tree-dump, specifically
-fdump-tree-optimized, but the "tail call" found there is emitted for
*all* targets. Debugged and ready to apply, putting it out for
consideration as someone will need it (or should use it) sooner rather
than later... Best committed rather than sitting in mail-archives so:
Ok to apply?

No planned usage.
