Add a --sanitize-regex REPLACEMENT=SOURCE option to the shared sanitization logic used by both PathSanitizingFileCheck and PathSanitizingDiff. Unlike --sanitize, SOURCE is treated as a regular expression used verbatim (no path normalization, regex escaping, or slash-compatibility substitution), so the sanitized string can be a regex and the replacement can reference capture groups. Regex sanitizations are applied after the literal path replacements so they can match already-sanitized text.

# Tests for the --sanitize-regex option shared by PathSanitizingFileCheck and

# PathSanitizingDiff. Unlike --sanitize, its SOURCE is treated as a regular

# A --sanitize-regex rewrites text matching the regex; the source is used as a

|
# regex (here [0-9]+), not as a literal string. --dry-run prints the result.

# REGEX: value = NUM

# The replacement may reference regex capture groups.

# --sanitize-regex composes with a literal --sanitize; literal paths are

# COMBINED: hash HASH in BUILD

|
# PathSanitizingDiff applies the same regex sanitization before diffing against
|
|
# the reference file, so a sanitized mismatch becomes a match.
