7068240: G1: Long "parallel other time" and "ext root scanning" when running specific \
                benchmark
Summary: In root processing, move the scanning of the reference processor's \
discovered lists to before RSet updating and scanning. When scanning the reference \
processor's discovered lists, use a buffering closure so that the time spent copying \
any reference object is correctly attributed. Also removed a couple of unused and \
                irrelevant timers.

7069863: G1: SIGSEGV running SPECjbb2011 and -UseBiasedLocking
Summary: Align the reserved size of the heap and perm to the heap region size to get \
a preferred heap base that is aligned to the region size, and call the correct heap \
reservation constructor. Also add a check in the heap reservation code that the \
                reserved space starts at the requested address (if any).

7039627: G1: avoid BOT updates for survivor allocations and dirty survivor regions \
                incrementally
Summary: Refactor the allocation code during GC to use the G1AllocRegion abstraction. \
Use separate subclasses of G1AllocRegion for survivor and old regions. Avoid BOT \
                updates and dirty survivor cards incrementally for the former.
