Because `-profile-correlate=binary` (though not added in this patch yet) will
be used by `TargetLoweringObjectFileImpl.cpp`, if keeping those flags
definitions in `InstrProfiling.cpp`, I got a linker error:
```
ld.lld: error: undefined symbol: llvm::ProfileCorrelate
>>> referenced by TargetLoweringObjectFileImpl.cpp
