Summary Dynamically generate a native call trunk per NativeFunction

https://bugs.webkit.org/show_bug.cgi?id=39252 regressed performance on i386, by adding an extra indirection to making a native call. By introducing per-NativeFunction thunks we can hard code the function pointer into the thunk so that it need not be loaded from the callee.
