+        adding repeated identifiers to the ParserArena's identifier list as people

+        Took some responsibilities away from NewSpace
+        https://bugs.webkit.org/show_bug.cgi?id=62325
+        
+        NewSpace is basically just an allocator now.
+        
+        Heap acts as a controller, responsible for managing the set of all
+        MarkedBlocks.
+        
+        This is in preparation for moving parts of the controller logic into
+        separate helper classes that can act on arbitrary sets of MarkedBlocks
+        that may or may not be in NewSpace.

+
+        Rather than doing multiple hash lookups as we currently
+        do when trying to identify keywords we now use an 
+        automatically generated decision tree (essentially it's
+        a hard coded patricia trie).  We still use the regular
+        lookup table for the last few characters of an input as
+        this allows us to completely skip all bounds checks.

+
+        When building inside the Qt source tree, qmake always append the mkspecs
