Deparse $obj->$meth=... [perl #62498]

When an lvalue method-as-variable is compiled, the method
op has a sibling that is an rv2cv:

a     <2> sassign vKS/2 ->b
3        <$> const[IV 1] s ->4
9        <1> entersub[t3] sKRMS*/NO(),TARG ->a
4           <0> pushmark s ->5
-           <1> ex-rv2sv sKM/1 ->6
5              <#> gvsv[*obj] s ->6
7           <1> method sK/1 ->8
-              <1> ex-rv2sv sK/1 ->7
6                 <#> gvsv[*meth] s ->7
8           <1> rv2cv /NO() ->9

Deparse didn’t know about it, and was iterating through the
children of entersub, thinking the last one was the method,
stopping at any item named ‘method_named’. So I modified it
to stop at ‘method’ as well.
