Fix windows build after r369894

Constructing a std::vector from a llvm::map_range fails on windows,
apparently because std::vector expects the input iterator to have a
const operator* (map_range iterator has a non-const one).

This avoids the cleverness and unrolls the map-loop manually (which is
also slightly shorter).
