Merged ZSTD_preserveUnsortedMark() into ZSTD_reduceIndex()

as it's faster, due to one memory scan instead of two
(confirmed by microbenchmark).

Note : as ZSTD_reduceIndex() is rarely invoked,
it does not translate into a visible gain.
Consider it an exercise in auto-vectorization and micro-benchmarking.
