Can Phi->adr_type() be narrowoop ?

[Vladimir Kozlov]

I am looking on failures where we missed an other checks for
EncodeP, DecodeN in EA. When EA do split unique types it walks
memory edges and can go over narrowoop memory (LoadN, for example).
And since we have LoadN we can have memory Phi with narrowoop type.
The question is can Phi->adr_type() be narrowoop also?
We never checks adr_type() for narrowoop and it returns TypePrt not Type.

Thanks,
Vladimir
