Tail calls are matched on the graph, with a dedicated tail call optimization that is actually testable. The instruction selection can still fall back to a regular if the platform constraints don't allow to emit a tail call (i.e. the return locations of caller and callee differ or the callee takes non-register parameters, which is a restriction that will be removed in the future). Also explicitly limit tail call optimization to stubs for now and drop the global flag.
