A corpus program feeds UTF-8 file contents (sync, fd, promise and Buffer
reads, BOM and CRLF lines) through regex test, exec span and full
results, match, matchAll, replace/replaceAll with substitutions and
callbacks, and split by regex, so the faster exec results and in-place
UTF-8 reads are covered beyond exec and readFileSync.
