PR 3545.
* tapsets.cxx (common_probe_entryfn_prologue): Added
'overload_processing' parameter, which defaults to true. If
overload_processing is set to false, doesn't output the
STP_OVERLOAD code.
(common_probe_entryfn_epilogue): Ditto.
(be_derived_probe_group::emit_module_decl): Set
overload_processing to false in calls to
common_probe_entryfn_prologue and common_probe_entryfn_epilogue
since begin/end probes shouldn't overload the system.
* translate.cxx (c_unparser::emit_common_header): Emit
STP_OVERLOAD global variables.
(translate_pass): Emit STP_OVERLOAD defines.
