Subzero: Use llvm::ilist<> for PhiList and AssignList.

This is toward the goal of pulling non-POD fields out of the CfgNode
class so that CfgNode can be arena-allocated and not leak memory.

For now, PhiList and AssignList are defined as InstList.  Ideally,
they would be ilist<> of InstPhi and InstAssign, but SFINAE happens.

BUG= none
