[PATCH] D148757: [clang] Follow user-provided order for prefix map

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

Can you add example options in the description and say how this patch is going to change it?

I think `std::map` is intended so that for `-f*-prefix-map` values, if both `a/b=...` and `a/b/c=...` match an input path, the longest wins, not the latest wins.
