  Log Message:
  -----------
  [NewGVN] Use ExprResult to add extra predicate users.

This patch updates performSymbolicPredicateInfoEvaluation to manage
registering additional dependencies using ExprResult. Similar to D99987,
this fixes an issues where we failed to track the correct dependency for
a phi-of-ops value, which is marked as temporary.

Fixes PR49873.
