It breaks integration with upstream re2 library on Chromium.
Without patching re2 library, with this define, it produces the
following error:
../../third_party/re2/re2/re2.h:254:5: error: expected identifier
POSIX, // POSIX syntax, leftmost-longest match
As we define POSIX on the command line, the C preprocessor changes
RE2::POSIX to nothing and thus break the compilation. :(

This is something I stumbled upon while looking at string copying we do (in spades) and did a simple change to not be constantly copying things around needlessly. There's a lot more that can be done in these files of course so this is sort of a reminder for future code edits that it's possible to design interfaces/function in a way that's more performance aware and avoid forcing creation of copies, while still being very simple. Also, we can use lambdas now :)
