Fix <rdar://problem/5595552> r27608 introduced a 20% increase in JS binary size, 4% increase in WebCore binary size

• This changes the way JS functions that use Lookup tables are handled. Instead using one class per function, which allowed specialization of the virtual callAsFunction method, we now use on class, PrototypeFunction, which takes a pointer to a static function to use as the implementation. This significantly decreases the binary size of JavaScriptCore (about 145k on an Intel only build) while still keeping some of the speedup r27608 garnered (SunSpider says this is 1.005x as slow, which should leave some wiggle room from the original 1% speedup) and keeps the functions implementations in separate functions to help with optimizations.
