Summary: Walk ICs to determine whether nmethods are dependent on
redefined classes.
See bug for more details. Tested with redefinition tests:
#redefinition tests.
make test TEST=open/test/hotspot/jtreg/vmTestbase/nsk/jvmti >&jvmti.out
make test TEST=open/test/hotspot/jtreg/vmTestbase/nsk/jdi >&jdi.out
make test TEST=open/test/hotspot/jtreg/runtime/RedefineTests >&redefine.out
make test TEST=open/test/jdk/java/lang/instrument >&instrument.out
make test TEST=open/test/jdk/com/sun/jdi >&jtreg.jdi.out
hs-tier1-6 as well as java/lang/instrument tests with -Xcomp.
