RFR (XS) 8223589: Build failures after JDK-8223534 (add back fixed test_markOop.cpp)

[Aleksey Shipilev]

Bug:
  https://bugs.openjdk.java.net/browse/JDK-8223589

The only use of assert_not_test_pattern is protected by _LP64, so default x86_32 build config fails
with "unused function". We could ifdef the definition too, but better yet, let's just use it on
!_LP64 path. Since this is a negative assert, it would not fail if we get the expected string wrong.
I had to look into markOopDesc::print_on and guess what the mark word printout on 32-bit would look
like. I mean not look like. Err...

Fix:
