clang-format: Fix bug in understanding string-label&value analysis.
While for <<-operators often used in log statments, a single key value
pair is always on the second operator, e.g.
llvm::errs() << "aaaaa=" << aaaaa;
It is on the first operator for plus- or comma-concatenated strings:
string s = "aaaaaaaaaa: " + aaaaaaaa;
(the "=" not counting because that's a different operator precedence)
