G1: region attribute remembered set state disagrees with actual remembered set state

Sporadically failing assertion was observed on PPC64 and x86_64:
assert(region_attr.needs_remset_update() == hr_obj->rem_set()->is_tracked()) failed: State flag indicating remset tracking disagrees (false) with actual remembered set (true) for region 62
with region:
| 62|0x00000000f3e00000, 0x00000000f3f00000, 0x00000000f3f00000|100%| O| |TAMS 0x00000000f3f00000, 0x00000000f3e00000| Complete

The assertion was introduced by JDK-8200545, but this behavior may be older.

Failing test on x86:

ran with -Xcomp -XX:-TieredCompilation and -Xms128m -Xmx288m.
