tsan: do not deadlock on fork
...
Currently correct programs can deadlock after fork, because atomic operations and async-signal-safe calls are not async-signal-safe under tsan.
With this change:
- if a single-threaded program forks, the child continues running with verification enabled (the tsan background thread is recreated as well)
- if a multi-threaded program forks, then the child runs with verification disabled (memory accesses, atomic operations and interceptors are disabled); it's expected that it will exec soon anyway
- if the child tries to create more threads after multi-threaded fork, the program aborts with error message
- die_after_fork flag is added that allows to continue running, but all bets are off

Macho-embedded: update build script for newer Clang behaviour.
...
Clang now uses the *-apple-macho triples for embedded targets using MachO. The
environment makes less pretences to be running an actual Mach kernel with all
the support that would imply, so a few changes are needed to the build scripts:
+ The Apple way of detecting endianness applies in all cases so drop the
__MACH__ test.
+ A quick rename since "darwin_embedded" no longer makes any sense. If there's
no Mach going on, there's certainly no Darwin.
+ Change how we test for support for a platform. The functions we build don't
need any SDK support (stdio.h, ...) so we don't need to check for it.

[asan] extend asan-coverage (still experimental).

- add a mode for collecting per-block coverage (-asan-coverage=2).
So far the implementation is naive (all blocks are instrumented),
the performance overhead on top of asan could be as high as 30%.
- Make sure the one-time calls to __sanitizer_cov are moved to function buttom,
which in turn required to copy the original debug info into the call insn.
Here is the performance data on SPEC 2006

Use the PRIu64 macro for printing a uint64_t.
...
Otherwise on (some) 64-bit systems, -Wformat will trigger a warning
because uint64_t is an 'unsigned long' not an 'unsigned long long'.
Consequently, PGOProfiling.c would fail to build if -Werror and
-Wformat are both enabled.

Fix an ODR violation in the sanitizer runtimes.
...
A helper function is a C++ function, and so even though one of the two
definitions is weak, it still technically triggers the ODR. Perhaps
these two definitions are ODR equivalent, but I'm not even confident in
that.
Instead, just define the function once, declare it as weak, and use
a wrapper that is clearly file-local. This avoids two definitions. Also
make the function extern "C" so that we can't even mess up the type
signature somehow or otherwise fail to match up the weak declaration
here with the interceptor defined elsewhere.

Per Nick Kledzik (http://llvm.org/bugs/show_bug.cgi?id=17976 ):
"""
For MacOSX, the labels in __cstring section should be 'L' labels, and the labels
in the __const section should be non-L or 'l' labels. The later ('l') will cause
the linker to remove the label in the final executable.
"""

tsan: remove in_rtl counter
...
This is intended to address the following problem.
Episodically we see CHECK-failures when recursive interceptors call back into user code. Effectively we are not "in_rtl" at this point, but it's very complicated and fragile to properly maintain in_rtl property. Instead get rid of it. It was used mostly for sanity CHECKs, which basically never uncover real problems.
Instead introduce ignore_interceptors flag, which is used in very few narrow places to disable recursive interceptors (e.g. during runtime initialization).

[Sanitizer] Add rudimentary support for using libbacktrace in symbolizer.
...
More steps are needed to actually make it usable:
* sanitizer runtimes should be compiled with -DSANITIZER_LIBBACKTRACE.
* libbacktrace headers should be installed.
* user has to manually link in libbacktrace.a into the executable.
We can easily solve the first two problems in the build system, but
detecting/linking libbacktrace to all the tests we have and end-user programs
is more challenging (and will unlikely work w/o Driver support).

Some linux headers are broken on older kernels.
Instead of depending on the constants and types from such headers directly,
we provide our own definitions and then verify them with compile-time

switching to some other way of testing on older kernels, or even disable the
tests as the last resort (after all, kernel interfaces are supposed to be
stable).
