[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).
Based on the patch by Jakub Jelinek!

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).

Summary:
Definitions we use in public sanitizer headers may

Moreover, we generally forbid to include any system headers (like <stdint.h>)
in sanitizer runtime headers. This leads to inevitable duplication of selected
interface function declarations, but we decided to live with it.

[ASan] Don't call __asan_init() from certain interceptors on Darwin.
...
Fixes http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58994 , which hadn't
manifested in LLVM because libclang_rt.asan_osx_dynamic.dylib used to depend on
the Foundation framework.
Without that dependency some interceptors may be called from the system
libraries before libSystem_initializer() is called, which lead to assertion
failures in sanitizer_mac.cc (_NSGetEnviron() returns NULL).
To fix the problem we fall back to the original functions in the common
libsanitizer interceptors and the __cxa_atexit() interceptor on Darwin.
This patch also prints a better error message in the case _NSGetEnviron()
returns NULL.

[ASan] Add CMake configs for libclang_rt.asan_iossim_dynamic.dylib
...
CMake changes to build the ASan runtime for the iOS simulator. This is a universal library targeting the same architectures as the OSX ASan runtime does, thus the iossim version can't live in the same universal libclang_rt.asan_osx_dynamic.dylib
The difference between the OSX and iossim builds is in the -mios-simulator-version-min and -ios_simulator_version_min flags that tell Clang to compile and link iossim code.
The iossim runtime can only be built on a machine with both Xcode and the iOS Simulator SDK installed. If xcodebuild -version -sdk iphonesimulator Path returns a nonempty path, it is used when compiling and linking the iossim runtime.

Summary:
TSan and MSan need to know if interceptor was called by the
user code or by the symbolizer and use pre- and post-symbolization hooks
for that. Make Symbolizer class responsible for calling these hooks instead.
This would ensure the hooks are only called when necessary (during
in-process symbolization, they are not needed for out-of-process) and
save specific sanitizers from tracing all places in the code where symbolization
will be performed.

Overhaul the symbolizer interface.
...
This moves away from creating the symbolizer object and initializing the
external symbolizer as separate steps. Those steps now always take place
together.
Sanitizers with a legacy requirement to specify their own symbolizer path
should use InitSymbolizer to initialize the symbolizer with the desired
path, and GetSymbolizer to access the symbolizer. Sanitizers with no
such requirement (e.g. UBSan) can use GetOrInitSymbolizer with no need for
initialization.
The symbolizer interface has been made thread-safe (as far as I can
tell) by protecting its member functions with mutexes.
Finally, the symbolizer interface no longer relies on weak externals, the
introduction of which was probably a mistake on my part.

__ARM_ARCH_EXT_IDIV__ is the define that ARM is using to indicate the presence
of hardware integer divide (sdiv/udiv). Previously, this code was only being
invoked for processors marked 7S. We now can correctly generate hardware
divides on cortex-a15 devices.

[msan] Fix invalid origin copying.
...
Origin copying may destroy valid origin info. This is caused by
__msan_copy_origin widening the address range to the nearest 4-byte aligned
addresses both on the left and on the right. If the target buffer is
uninitialized and the source is fully initialized, this will result in
overriding valid origin of target buffer with stale (possibly 0) origin of the
source buffer.
With this change the widened origin is copied only if corresponding shadow
values are non zero.

tsan: add annotations to ignore synchronization operations

The annotations are AnnotateIgnoreSyncBegin/End,
may be useful to ignore some infrastructure synchronization

[sanitizer] Fix the parent liveness check in StopTheWorld.
...
Comparing the parent PID with 1 isn't sufficient to ensure the parent is alive,
because of prctl(PR_SET_CHILD_SUBREAPER, ...). Compare with the real parent's
recorded PID instead.

[sanitizer] Fix deadlock in StopTheWorld.
...
The tracer thread in StopTheWorld could wait on a mutex forever if the parent
process died before unlocking it. Use PR_SET_PDEATHSIG so that the parent would
kill the child in this scenario.

[sanitizer] Do not break the CFI unwind chain in clone().
...
Fixes build on clang 3.2, which doesn't support cfi_undefined. This change
doesn't seem to break the slow unwinder. Even if it does, the worst thing that
could happen is that we would not see a backtrace when a fatal error happens
under StopTheWorld.

asan/msan/tsan: fix broken linux syscalls

Currently the following source code:
u64 NanoTime() {
kernel_timeval tv = {};
internal_syscall(__NR_gettimeofday, &tv, 0);
return (u64)tv.tv_sec * 1000*1000*1000 + tv.tv_usec * 1000;
}
generates the following assembly:

tsan: ignore interceptors coming from specified libraries
...
LibIgnore allows to ignore all interceptors called from a particular set
of dynamic libraries. LibIgnore remembers all "called_from_lib" suppressions
from the provided SuppressionContext; finds code ranges for the libraries;
and checks whether the provided PC value belongs to the code ranges.
Also make malloc and friends interceptors use SCOPED_INTERCEPTOR_RAW instead of
SCOPED_TSAN_INTERCEPTOR, because if they are called from an ignored lib,
then must call our internal allocator instead of libc malloc.
