RFR (S) 8220512: Deoptimize redefinition functions that have dirty ICs

[coleen.phillimore at oracle.com]

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.
