    PR14378: Better @entry squashing in kprobe.function
    
    @entry is only valid in .return, but kprobe_var_expanding_visitor was
    expanding it blindly.  Then kprobe_derived_probe was failing its
    assertion that add_call_probe only happens with has_return.  So the test
    semko/entry04.stp was failing as it should, but rather ungracefully with
    an "Assertion `has_return' failed" abort.
    
    * tapsets.cxx (kprobe_var_expanding_visitor): Add a has_return member so
      we know our current context.
      (kprobe_var_expanding_visitor::visit_entry_op): Guard @entry expansion
      on has_return, the same way dwarf_var_expanding_visitor does.
