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.
* elaborate.cxx (dead_assignment_remover::visit_expr_statement):
Correct stmt token after possible expression rewriting.
* tapsets.cxx (visit_target_symbol): Create naming convention
to recognize $target-synthesized functions.
* translate.cxx (emit_locks, emit_unlocks): New functions to
emit lock/unlock sequences at the outermost level of a probe.
(emit_probe): Call them.
(varlock_*): #if-0 out the lock code generation. Later, these
classes should be removed.
(translate_pass): Emit read_trylock() kludge macro for old kernels.
