All intrinsic code generating words signatures are changed from ( node
-- ) to ( block node -- block' ) so the current block is now always
passed on the stack.
The emit-node generics signature is changed to ( block node -- block' )
so that it always returns the next block to operate on. Signature for a
lot of related words are changed similarily. Now there is only a few
basic-block usages left.
