SA had a bunch of vtable related code that searched for the vtable pointer of a hotspot object in a few places. This was all related to weird ways that Solaris would store the vtable pointer. In the case of https://bugs.openjdk.java.net/browse/JDK-8269830, this extra vtable searching code introduced a bug in BasicTypeDataBase.addressTypeIsEqualToType(). Since we don't support Solaris anymore, this the bug was fixed by removing this Solaris support. At the time I fixed JDK-8269830, I noticed that BasicTypeDataBase.findDynamicTypeForAddress() had similar logic for vtable searching, although didn't seemed to be causing any bugs at the time. I filed JDK-8269838 to eventually clean it up, and that's what this PR is doing.
------------- Commit messages: - Strip out code that looks for vtable pointers in locations other than the 1st word of the object.
