6755988: G1: assert(new_obj != 0 || ... "should be forwarded")
Summary: A TLAB became large enough to be considered a humongous object allowing \
multiple objects to be allocated in a humongous region, which violates a basic \
assumption about humongous regions. The changes ensure that TLABs cannot be regarded \
as humongous.
