Core j.l.i classes are preloaded during VM startup in order to avoid
possible deadlock when accessing JSR292-related functionality from
multiple threads. After LF sharing-related changes, FILL_ARRAYS and
ARRAYS are initialized too early. It affects startup time & footprint of
applications that don't use JSR292.
The fix is to move these fields into MHI.Lazy class, thus delaying their
initialization to the first usage of JSR292 API.
Testing: failing test, manual (measured HelloWorld app startup time;
compared -XX:+PrintCompilation logs)
