G1 evolution/maturing

[Jon Masamitsu]

Alex,

Over the last year there has been work to make G1 more stable,
move more work to the concurrent phases, simplify some
code to improve performance and adjust G1 policy
for choosing regions to collect.  Large heaps have typically
been used in measuring performance so there is that
bias in the improvements (meaning we probably don't
have good numbers on how much performance with
smaller heaps have changed).  7u4 is the release to
try.
