Summary: lcov tracefiles are used by various coverage reporting tools and build systems (e.g., Bazel). It is a simple text-based format to parse and more convenient to use than the JSON export format, which needs additional processing to map regions/segments back to line numbers. It's a little unfortunate that "text" format is now overloaded to refer specifically to JSON for export, but I wanted to avoid making any breaking changes to the UI of the llvm-cov tool at this time.
