You're right.  Here is a new webrev:

I'm not sure if the LIR_OpDelay::is_method_handle_invoke is good name
choice.

Additionally I changed ciMethod::is_method_handle_invoke to use the
holder and method name to be able to call it on unloaded methods.  John
hasn't replied yet on my email if that's OK but my extensive testings
show that it should be OK.
