Fixed SEA IR bugs.
Bug 1: The type inference visitor did not clear type between visits,
so all instructions had types attached because of this.
Bug 2: The .dot file genration was missing phi ssa edges because
the GetSSAProducers map hasn't got the same semantics.
(Phi Nodes use a single register which has multiple definitions,
not multiple registers with a single definition each)
Bug 3: Added the SE IR id in the textual representation of nodes
in the .dot representation to ease debugging.
