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? -- >8 -- No planned usage.
