adamk b767329b37 Fix Map::AsArray to properly iterate over the backing store 
Old code failed to walk over deleted elements, instead treating
deleted elements as "undefined" in the output array.

This is the Map equivalent of commit 2d9bfe9ad5.

Also micro-optimized the loops to avoid an extra call to KeyAt()
and used a direct hole comparison instead of calling IsTheHole().
