Jake Hughes fc2d1d090d [heap] Add flag for pinning pages 
In order to support conservative stack scanning, we need to be able to
pin pages if they're pointed to by an ambiguous pointer. This CL lets us
do this by providing an IS_PINNED flag which, when enabled, prevents a
page from being selected as an evacuation candidate during compaction.
