8893530f3a 6812428: G1: Error: assert(ret || obj_in_cs(obj),"sanity") 
The length of the fast cset test vector is decided at the beginning of a GC, but more regions can be added during the GC. The simple fix is to set the length of the fast cset test vector to the max.

e7d899910b 6810698: G1: two small bugs in the sparse remembered sets 
The _expanded flag of the sparse RSets is not reset and this can leave a RSet in an inconsistent state if it is expanded more than once. Also, we should be iterating over the _cur, instead of the _next, sparse table

72bfacbd95 6797870: Add -XX:+{HeapDump,PrintClassHistogram}{Before,After}FullGC 
Call newly created CollectedHeap::dump_{pre,post}_full_gc before and after every stop-world full collection cycle on GenCollectedHeap and ParallelScavengeHeap. (Support for G1CollectedHeap forthcoming under CR 6810861.) Small modifications to existing heap dumping and class histogram implementation, especially to allow multiple on-the-fly histos/dumps by the VM thread during a single safepoint.
