This patch updates performSymbolicPredicateInfoEvaluation to manage
registering additional dependencies using ExprResult. Similar to D99987 <https://reviews.llvm.org/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.
