[asan] when reporting an ODR violation, also print the stack traces where the globals have been registered (thus show the name of shared library or exe to which the global belongs). The reports become a bit too verbose but I do not see any *simple* way to make them more compact. This should be especially helpful when the ODR happens because the same .cc file is used twice in the project in differend DSOs

[msan] Fix handling of multiplication by a constant with a number of trailing zeroes.
...
Multiplication by an integer with a number of trailing zero bits leaves
the same number of lower bits of the result initialized to zero.
This change makes MSan take this into account in the case of multiplication by
a compile-time constant.
We don't handle the general, non-constant, case because
(a) it's not going to be cheap (computation-wise);
(b) multiplication by a partially uninitialized value in user code is
a bad idea anyway.
Constant case must be handled because it appears from LLVM optimization of a
completely valid user code, as the test case in compiler-rt demonstrates.

compiler-rt: prefer thumb over ARM
...
When possible, use Thumb or Thumb-2 over ARM instructions. This is particularly
important for pure-Thumb environments (e.g. Windows on ARM). Although, it is
possible to conditionalise this for that target specifically, this is available
on most newer ARM CPUs, and the code remains compatible with older CPUs with no
adverse effects. It therefore feels better to always prefer Thumb when
possible.

Init-order and use-after-return modes can currently be enabled

The only problem I see is that users won't be able to disable extra
instrumentation for init-order and use-after-scope by a top-level Clang flag.
But this instrumentation was implicitly enabled for quite a while and
we didn't hear from users hurt by it.

Instructions from __nodebug__ functions don't have file:line

intrinsics (SSE and other) from <*intrin.h> clang headers _never_

With this change, an instruction without !dbg metadata gets one from
the call instruction when inlined.

tsan: make positive tests more robust
...
Add a script that is used to deflake inherently flaky tsan tests.
It is invoked from lit tests as:
%deflake %run %t
The script runs the target program up to 10 times,
until it produces a tsan warning.

tsan: optimize memory access functions
...
The optimization is two-fold:
First, the algorithm now uses SSE instructions to
handle all 4 shadow slots at once. This makes processing
faster.
Second, if shadow contains the same access, we do not
store the event into trace. This increases effective
trace size, that is, tsan can remember up to 10x more
previous memory accesses.
Perofrmance impact:
Before:
[ OK ] DISABLED_BENCH.Mop8Read (2461 ms)
[ OK ] DISABLED_BENCH.Mop8Write (1836 ms)
After:
[ OK ] DISABLED_BENCH.Mop8Read (1204 ms)
[ OK ] DISABLED_BENCH.Mop8Write (976 ms)
But this measures only fast-path.
On large real applications the speedup is ~20%.
Trace size impact:
On app1:
Memory accesses : 1163265870
Including same : 791312905 (68%)
on app2:
Memory accesses : 166875345
Including same : 150449689 (90%)
90% of filtered events means that trace size is effectively 10x larger.
