DAG dump readability

[Mikael Lyngvig]

Perhaps you should consider to use #ID instead of NodeID (#43 instead of
Node43) as it appears that there may be quite a few nodes in each line and
you thereby can save three characters per node.  But as you are already
saving a few characters per node, it may be a silly suggestion.  Just my
two pennies.

>   0x3adf4e0: v4i32,ch = load 0x3ab64c0, 0x3ab5680, 0x3abaee0 <LD16[bitcast
> ([4 x i32]* @f to <4 x i32>*)](align=4)(tbaa=<badref>)> [ORD=47] [ID=-3]
>
> After:
>   Node47: v4i32,ch = load Node7, Node46, Node26<i32 undef> <LD16[bitcast
> ([4 x i32]* @f to <4 x i32>*)](align=4)(tbaa=<badref>)> [ORD=47] [ID=-3]
>
> Features:
>   * Possibility to replace 0xCRAZYNUM with something more
>     readable (Node<Num>).
>     You can also setup to output both CRAZYNUM and Node<Num>.
>   * Constants, registers and undef could be inlined. So you don't need
>     to lookup top part of dump just to realize that 0x3abaee0 is undef.
>     It could be inlined in hint mode, or substitution mode.
>     In last case you will get next output:
>   Node47: v4i32,ch = load Node7, Node46, i32 undef <LD16[bitcast ([4 x
> i32]* @f to <4 x i32>*)](align=4)(tbaa=<badref>)> [ORD=47] [ID=-3]
>
> Will wait you reviews, remarks and questions.
