begin_move_insn can be easily fixed, the question is why we try to schedule the
tail call insn over the restore of r12, which is a call saved register and
therefore has to be restored.

Perhaps we should just consider tail calls as full barriers like asm volatile
etc., scheduling some insn after them doesn't make much sense, that is just a
fancy way of removing them and I'd hope that insn removal is the job of DCE and
similar optimizations, but not of the scheduler.
