        PR 2341 (partial fix)
        * elaborate.h (struct derived_probe): Added needs_global_locks()
        member function.  Unless overridden, will return true indicating
        that this probe needs locks around global variable references.
        * tapsets.cxx (struct be_derived_probe): Added override of default
        needs_global_locks() returning false.  begin/end probes don't
        need locks around global variables, since they aren't run
        concurrently with any other probes.
        * translate.cxx (c_unparser::emit_common_header): Updated
        probe_contents logic to match the logic in emit_probe.
        (c_unparser::emit_probe): Added whether the probe needs global
        variable locks to the probe string (that helps eliminate duplicate
        probes).  The generated C changes based on whether or not global
        variable locks are needed, but the pass 2 output doesn't differ
        between a probe that needs global variable locks and one that
        doesn't.  If the probe doesn't need global variable locks, doesn't
        output them.
