Message:

JSC objects need to know their own cell size at runtime.

Reviewed by Geoffrey Garen.

Added the cellSize field to ClassInfo and the static calculation of
size of each class to the CREATE_METHOD_TABLE macro, which will be
renamed in a followup patch to make its name match its broader use.

Also added a few ClassInfo structs so that each object that is allocated has its
correct size.

• JavaScriptCore.exp:
• runtime/ClassInfo.h:

Changed JSByteArray s_defaultInfo to s_info so that the template will get the
correct ClassInfo struct from it when it's allocated.
