Enable moving classes.

Slight reduction in Zygote size, memory savings are in the noise.
Before: Zygote size: 8739224
After: Zygote size: 8733568

Fixed a bug where we didn't set the concurrent start bytes after
switching the allocator from bump pointer to ROSAlloc in the
zygote. This caused excessive memory usage.

Added the method verifiers as roots to fix an issue caused by
RegTypes holding a Class*.

Added logic to clear card table in the SemiSpace collector, this
reduces DalvikOther from ~2400k -> ~1760k when using the SemiSpace
collector.

Added a missing lock to the timing loggers which caused a rare
one time crash in std::set.
