hg: valhalla/valhalla: 8206002: [lworld] ValueTypesTest fails with 'assert(Universe::heap()->is_in_closed_subset(o)) failed: should be in closed'.

[Tobias Hartmann]

I've pushed this directly because the fix is trivial: We did not emit GC barriers for stores to
non-flattened value type fields because T_VALUETYPE was not treated as oop.

I've also added -Xcomp to the corresponding test.

Thanks,
Tobias
