f482091133 7039627: G1: avoid BOT updates for survivor allocations and dirty survivor regions incrementally 
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.

f7d3d2b63e 7069863: G1: SIGSEGV running SPECjbb2011 and -UseBiasedLocking 
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).

144fb9dc25 7068240: G1: Long "parallel other time" and "ext root scanning" when running specific benchmark 
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.
