-This change adds support for parsing the output of gcov's intermediate
-JSON file format as implemented by GCC version 9.
-
-Note: The way that the intermediate file format support is implemented
-in geninfo removes the need to parse .gcno files directly. Since geninfo
-does not include support for parsing GCC 9 .gcno files, using the
-intermediate format is the only option for geninfo to collect coverage
-data generated by GCC version 9.
