Clang LTO uses __UNIQUE_ID() to generate some uniquely named wrapper functions, like initstubs. If they're uncorrelated, prevent them from being reported as new functions and included unnecessarily.
Note that dont_correlate() already includes prefix functions, so prefix functions are still being ignored here.
