    [sanitizer] No THREADLOCAL in qsort and bsearch

    qsort can reuse qsort_r if available.
    bsearch always passes key as the first comparator argument, so we
    can use it to wrap the original comparator.

    tsan: avoid extra call indirection in unaligned access functions

    Currently unaligned access functions are defined in tsan_interface.cpp
    and do a real call to MemoryAccess. This means we have a real call
    and no read/write constant propagation.

    Unaligned memory access can be quite hot for some programs
    (observed on some compression algorithms with ~90% of unaligned accesses).

    Move them to tsan_interface_inl.h to avoid the additional call
    and enable constant propagation.
    Also reorder the actual store and memory access handling for
    __sanitizer_unaligned_store callbacks to enable tail calling
    in MemoryAccess.

    Depends on D107282.

    tsan: optimize test-only barrier

    The updated lots_of_threads.c test with 300 threads
    started running for too long on machines with low
    hardware parallelism (e.g. taskset -c 0-1).
    On lots of CPUs it finishes in ~2 secs. But with
    taskset -c 0-1 it runs for hundreds of seconds
    effectively spinning in the barrier in the sleep loop.

    We now have the handy futex API in sanitizer_common.
    Use it instead of the passive spin loop.
    It makes the test run only faster with taskset -c 0-1,
    it runs for ~1.5 secs, while with full parallelism
    it still runs for ~2 secs (but consumes less CPU time).

    Depends on D107131.
