Log message:

	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.
