        Description

        This is a follow-up to 6998541.

        Customers have observed that inlining some kinds of method handles tickles unexpected paths in methodHandleWalk.cpp.

        Known cases:

        - http://mail.openjdk.java.net/pipermail/mlvm-dev/2011-May/003060.html
        - http://mail.openjdk.java.net/pipermail/mlvm-dev/2011-May/003055.html
        - asSpreader adapters

        There should be "lose" calls on paths we don't expect, so the method handle walker can back out cleanly and fail the inlining.
