Summary: CoverageExporterJson::renderFiles accounts for most of the execution time given a large profdata file with multiple binaries. Proposed solution is to generate JSON for each file in parallel and sort at the end to preserve deterministic output. Also added flags to skip generating parts of the output to trim the output size. Patch by Sajjad Mirza (@sajjadm).
