Because of the way Bionic sets up signal stack frames, libc unwinder is unable

Luckily, libcorkscrew.so on Android implements an unwinder that can start with
a signal context, thus sidestepping the issue.

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

[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

This change allows to compile sanitizer sources so that *san runtime
will attempt to use libbacktrace and/or libiberty for symbolization
(instead of communicating with llvm-symbolizer).
I've tested this patch by manually defining SANITIZER_LIBBACKTRACE and/or
SANITIZER_CP_DEMANGLE, linking with necessary libraries and verifying that
all tests from ASan test suite work.
Based on patches by Jakub Jelinek!

[asan] Include <sys/stat.h> if __x86_64__ is defined
...
struct stat defined in <asm/stat.h> is incorrect for x32. <asm/stat.h>
is included to get struct __old_kernel_stat. But struct __old_kernel_stat
isn't used for x86-64 nor x32. This patch includes <sys/stat.h> instead
of <asm/stat.h> and comments out size check of struct __old_kernel_stat
for x86-64.

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.

[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).
