	PR 2060: lock elevation, mop-up
	* staptree.cxx (functioncall_traversing_visitor): Store a
	current_function pointer during traversal.
	(visit_embeddedcode): Use it to handle $target-synthesized functions.
	(varuse_collecting_visitor::visit_assignment): Correct l-lr typo.
	(visit_foreach_loop): Note added write on sorted foreach.
	(visit_delete_statement): Note as read+write.
	* staptree.h: Corresponding changes.

	Correct stmt token after possible expression rewriting.
	* tapsets.cxx (visit_target_symbol): Create naming convention

	emit lock/unlock sequences at the outermost level of a probe.
	(emit_probe): Call them.
