This patch adds a `--validate` option to the jar tool which can be used to
validate a jar file that might be malformed. For instance, if a jar is a
multi-release jar, it is malformed if different versions expose different APIs.
The implementation is straight forward since there already exists
I'll go ahead with this enhancement, and make sure the wording is open
to adding validation logic not related to multi-release jars in the future.

This patch speeds up MethodHandle.asCollector handles where the array type is
not Object[], as well as speeding up all collectors where the arity is greater
than 10.

methods for collecting arguments into an Object[],
