Remove first GC pause.
Fixed error where we were prefetching the address of address of
objects.
Remove first paused by removing get dirty cards and replacing it
with card aging. We now age the cards before doing the checkpoint
instead of clearing them. This lets us know which cards were
dirtied before the start of the GC and which cards were dirtied
after.
Optimized FreeList slightly.
