libsanitizer: Bump asan/tsan versions
Bump asan/tsan versions for upstream commits:

[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.
