The name is part of the fixed structure of CONSTANT_InvokeDynamic, which is
modeled on CONSTANT_Methodref, and therefore contains a CONSTANT_NameAndType.
Whether you want the name or not, it's in there.
Minimally, an indy instruction could get by with a signature, a BSM, and 0 or
more static arguments. Adding the name makes the new CP entry a little more
similar to existing ones.
If you put the name string in the argv, you'd need a CONSTANT_Utf8 and a
CONSTANT_String. In the current design, you instead have a CONSTANT_NameAndType
and a CONSTANT_Utf8. So the CP entry pressure is the same in most cases.
