3cd36270b7 7097002: G1: remove a lot of unused / redundant code from the G1CollectorPolicy class
Major cleanup of the G1CollectorPolicy class. It removes a lot of unused fields and methods and also consolidates replicated information (mainly various ways of counting the number of CSet regions) into one copy.

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.
