V4 IR: Store the phi-node parameters directly in the class.
Every time one of the paramets was accessed, the chain of loads was:
phi->d->incoming->heapdata[i]
Now it is:
phi[i + offsetof(incoming)]
This also removes at least one malloc (for the Data), and usually two
(when the number of parameters is <= 4, which is most of the cases).
