Remove novellonly.

It appears that the ObjC compiler moves some things around from the predicted
argument ordering, for the method in question which would normally be:

objc_msgSend (NSEventClassPtr, Selector, Mask, BlockPtr)

we're getting:

    movl    %edx, 16(%esp)
    movl    $11, 8(%esp)
    movl    $0, 12(%esp)
    movl    %eax, 4(%esp)
    movl    %ecx, (%esp)

Which is basically:

objc_msgSend (NSEventClassPtr, Selector, Mask, 0x0, BlockPtr)
