Matt, please try to evaluate -fork=0 (default) vs -fork=1 using the fresh clang

- 24 hour A/B test of
-fork=0vs-fork=1, most benchmarks - 50 hour A/B test of
-fork=0vs-fork=1, vorbis only
In general fork modes seems to start off much slower than the normal mode, but catches up and wins for benchmarks that crash a lot (e.g., pcre2), while significantly lagging behind for less buggy benchmarks.
