9ca97e4c78 7051430: CMS: ongoing CMS cycle should terminate abruptly to allow prompt JVM termination at exit 
It turns out that there is no need to explicitly stop CMS since the JVM is taken down at a terminal safepoint during which CMS threads are (terminally) inactive. This  will need to be revised if and when we evolve in the future to a point where we allow JVM reincarnation in the same process, but those changes will be much more sweeping than just terminating CMS threads. The unused ::stop() methods will be removed in a separate CR. Also include in this CR is the fix for a small typo in the spelling of UseGCLogFileRotation in a message in arguments.cpp, brought to our attention by Rainer Jung and reviewed by minqi.

6804436: G1: heap region indices should be size_t

A series of fixes and improvements to the HeapRegionSeq class: a) replace the _regions growable array with a standard C array, b) avoid de-allocating / re-allocating HeapRegion instances when the heap shrinks / grows (fix for 7042285), c) introduce fast method to map address to HeapRegion via a "biased" array pointer, d) embed the _hrs object in G1CollectedHeap, instead of pointing to it via an indirection, e) assume that all the regions added to the HeapRegionSeq instance are contiguous, f) replace int's with size_t's for indexes (and expand that to HeapRegion as part of 6804436), g) remove unnecessary / unused methods, h) rename a couple of fields (_alloc_search_start and _seq_bottom), i) fix iterate_from() not to always start from index 0 irrespective of the region passed to it, j) add a verification method to check the HeapRegionSeq assumptions, k) always call the wrappers for _hrs.iterate(), _hrs_length(), and _hrs.at() from G1CollectedHeap, not those methods directly, and l) unify the code that expands the sequence (by either re-using or creating a new HeapRegion) and make it robust wrt to a HeapRegion allocation failing.
