8272400: [lworld] serviceability/sa/CDSJMapClstats.java fails: No suitable match for type of address

[iklam]

This is a fix in CDS and SA to get CDSJMapClstats.java (and a bunch of other SA tests) to pass:

• Implement skeletal FlatArrayKlass and InlineKlass types in SA
• Implement the CDS C++ vtable lookup of these two types.

After this fix, only 2 out of 191 tests in test/hotspot/jtreg/serviceability/ are still failing.

However, support of these two types are incomplete in SA, so programs that try to use the SA APIs to access VM internals will not work. The full SA support of inlined types will be done separately in https://bugs.openjdk.java.net/browse/JDK-8205036
