JSC objects need to know their own cell size at runtime.
​https://bugs.webkit.org/show_bug.cgi?id=69390

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.

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