Subject: Include algorithm for suffix_array_index.cc

This is required due to the use of std::mismatch. This
file may have compiled before due to a transitive inclusion
of the <algorithm> header. However, recent changes to LLVM ToT
will prevent these transitive inclusions from happening.

We identified this problem due to emerging bsdiff with `llvm-next`
in ChromeOS.
