at all.

(save_for_inline_copying):  When making copies of NOTE_INSN_BLOCK_END
notes, stash a "forwarding" pointer in the original to point to the
copy.  Also, when all BLOCKs & insns for a function have been copied,
call `adjust_copied_decl_tree' to fixup the end_note pointers in the
copied BLOCKs.
