2c3f0e54 - [CodeGen] Preserve branch weights from PGO profile during instruction selection at -O0 (#161620)

[CodeGen] Preserve branch weights from PGO profile during instruction selection at -O0 (#161620) Branch probabilities from PGO profile data were not preserved during instruction selection at -O0 because BranchProbabilityInfo was only requested when OptLevel != None.
