Clean-up heap spaces.

We now use the CMS collector instead of the semispace collector when
the phone is booting. We still perform compaction during the zygote
space creation. This reduces time spent in GC by ~2s during boot
and doesn't affect zygote space size.

Changed the space creation logic to create the temp space when a
background transition occurs.

Added a flag to each space which is true if you are allowed to
move objects that are within this space.

Removed SwapSemiSpaces call from the semi space collector, it is now
the job of the caller to do this with threads suspended. This
simplifies the logic in the zygote compaction / heap transition code
since these do not copy from one semispace to another.

Added Space::Clear to RosAllocSpace and DlMallocSpace. This greatly
simplifies the code used for collector transitions.

Time spent in GC creating zygote space:
Before: 3.4s, After: 1.28s
No change in zygote space size.
