8000740: remove LinkWellKnownClasses
Reviewed-by:

With 8000263 LinkWellKnownClasses was turned on by default to see if
it works. Nightly testing showed that various JDI and JVMTI tests fail
with LinkWellKnownClasses turned on, e.g.:

jdk/test/com/sun/jdi/NewInstanceTest.java 

To avoid future problems we remove the code altogether.

Additionally I resurrected some 292 code that is required when
building with JDK 6.
