As a follow up to commit d4c991d34c8c8568c
([clang-tidy][NFC] Apply const-correctness for auto 1/N (#213839)) we make sure 
to use a const reference when iterating of FixLocations.

As indicated by -Wrange-loop-construct this prevents a copy from type 
'std::pair<clang::SourceLocation, bool> const'.
