The frontend supports this via new options -index-unit-output-path and -index-unit-output-path-filelist that mirror -o and -output-filelist. These are intended to allow sharing index data across builds in separate directories (so different -o values) that are otherwise equivalent as far as the index data is concerned (e.g. an ASAN build and a non-ASAN build) by supplying the same -index-unit-output-path for both. This change updates the driver to add these new options to the frontend invocation 1) when a new "index-unit-output-path" entry is specified for one or more input files in the -output-file-map json or 2) if -index-file is specified, when a new -index-unit-output-path driver option is passed.
