    PR13200: skip prologue searching for *.function(ADDR).return probes
    
    Prologue searching has to be suppressed for all kretprobes/uretprobes
    address calculations, or else the *retprobes facility can overwrite
    valid stack frame data instead of return addresses.
    
    * tapsets.cxx (query_addr, query_func_info): Perform prologue analysis
      but verbosely ignore results, for .return probes.
