Subzero: Pull the node name out of the node structure.

Instead, non-empty node names are kept in a single vector in the Cfg
object.

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.

Also, actual setting of the node name is now guarded by ALLOW_DUMP.

BUG= none
