phi-sources can only have a single user (or none)
Currently, OP_PHISOURCES have a list as member, 'phi_users',
that should link to all phi-nodes using them but:
*) phi-sources are never shared between phi-nodes
*) this list is useless because it's only created during liveness
and not used after.
So, replace the list by a simple pointer to hold the unique phi-node
using it and keep this link updated during all its lifetime.
