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.

6921710: G1: assert(new_finger >= _finger && new_finger < _region_limit,"invariant")
Summary: If CM task was aborted while scanning the last object of the specified region and the size of that object is equal to bitmap's granularity then the next offset would be equal or over the region limit which is exactly what the assertion states.
