ValueMapper: Resolve uniquing cycles more aggressively

As a follow-up to r244181, resolve uniquing cycles underneath distinct
nodes on the fly.  This prevents uniquing cycles in early operands from
affecting later operands.  It also removes an iteration through distinct
nodes' operands.

No real functional change here, just more prompt resolution of temporary
nodes.
