7000578: CMS: assert(SafepointSynchronize::is_at_safepoint()) failed: Else races are \
                possible
Summary: Weakened assert in onj_is_alive() to allow its use at initialization time \
when is_at_safepoint() normally reports false; added some related asserts to check \
                order of is_init_completed() after Universe::is_fully_initialized().

6978187: G1: assert(ParallelGCThreads>  1 || n_yielded() == _hrrs->occupied()) \
                strikes again
Summary: An evacuation failure while copying the roots caused an object, A, to be \
forwarded to itself. During the subsequent RSet updating a reference to A was \
processed causing the reference to be added to the RSet of A's heap region. As a \
result of adding to the remembered set we ran into the issue described in 6930581 - \
the sparse table expanded and the RSet scanning code walked the cards in one instance \
of RHashTable (_cur) while the occupied() counts the cards in the expanded table \
                (_next).
