JDK-8284161 added special printing when oopDesc contains badHeapWordVal or badMetaWordVal. However these two cases do not print a trailing newline. The previous behaviour was to always use a trailing newline.

Propose making this consistent with *klass::oop_print_on and InstanceStackChunkKlass::print_chunk, that both uses a trailing newline.

This new behaviour messes up some printing code, e.g. can be seen in print_location when printing hs_err files which assumes that it always prints a trailing newline.
