A little more Heap refactoring
​https://bugs.webkit.org/show_bug.cgi?id=53577

SunSpider reports no change.

Split out MarkedBlock into its own file / class.

Did the following renames:

isCellMarked => isMarked
checkMarkCell => testAndSetMarked
markCell => setMarked
cellOffset => cellNumber
collectorBlock => blockFor
