When using `compiler-rt/lib/asan/scripts/asan_symbolize.py` with Python 3.12, two syntax warnings concerning invalid escape sequences are being reported:
```
[...]/asan_symbolize.py:319: SyntaxWarning: invalid escape sequence '\('
match = re.match("^(.*) \(in (.*)\) \((.*:\d*)\)$", atos_line)
[...]/asan_symbolize.py:544: SyntaxWarning: invalid escape sequence '\('
"^( *#([0-9]+) *)(0x[0-9a-f]+) *(?:in *.+)? *\((.*)\+(0x[0-9a-f]+)\)
```
This is caused by a change in behaviour in Python 3.12 to eventually make such things syntax errors (see [release notes](https://docs.python.org/3/whatsnew/3.12.html#other-language-changes)).
I'd be happy to file a PR to fix this, but I'm not sure how the regexes are supposed to look / why the invalid escape sequences have been added in the first place.
