Previously, when using `-analyze-function` to target a specific function, the analyzer would incorrectly report "Every top-level function was skipped" even when the function was successfully analyzed by syntax-only checkers. This happened because `NumFunctionsAnalyzed` only counted path-sensitive analysis, not syntax-only analysis. The misuse detection logic would see 0 functions analyzed and incorrectly conclude the function wasn't found.
