Not by prefix, but you can insert the paths and its parents on a
StringMap ($LLVM/include/llvm/ADT/StringMap.h) then decompose your file
path and lookup the resulting prefix paths.

But there is no need for fancy data structures: your vector<string>
(sorted) should be fast enough.

Normalizing the paths first would make things easier. Also, keep in
mind the case-insensitive file systems.
