RFR JDK-8129547: Excess entries in BootstrapMethods with the same (bsm, bsmKind, bsmStaticArgs), but different dynamicArgs

[Maurizio Cimadamore]

Hello,

This is a fix for:

https://bugs.openjdk.java.net/browse/JDK-8129547

which has been discussed on this list recently. The problem is sometimes 
javac generates duplicate BSM entries in the bootstrap method attribute, 
due to the fact that the equals/hashing function for such entries takes 
into account the invokedType while it shouldn't.

A webrev with the fix is here:

Feedback welcome.

Cheers
Maurizio
