RFR: 8271063: Print injected fields for InstanceKlass [v3]

[Coleen Phillimore]

> I added code to print the injected fields in InstanceKlass.  I also removed field offset sorting for do_nonstatic_fields because it's not necessary when used for purposes other than printing the fields.  I also added a gtest.
> Tested with tier1 all Oracle platforms, tier2-3 on linux-x64-debug, windows-x64-debug.
