Visits a method instruction. A method instruction is an instruction that invokes a method.

@param opcode the opcode of the type instruction to be visited. This opcode is either
INVOKEVIRTUAL, INVOKESPECIAL, INVOKESTATIC or INVOKEINTERFACE.
@param owner the internal name of the method's owner class (see {@link
Type#getInternalName()}).
@param name the method's name.
@param descriptor the method's descriptor (see {@link Type}).
@param isInterface if the method's owner class is an interface.
