[asan] Android test runner for ASan lit tests.
...
This change replaces 32- and 64- bit config.in-s with a single config template
that is used to generate both 32 and 64 bits configs as well as the new
arm-android config. Arm-android config is special because it can run tests on
a remote device over adb (android debug bridge).
We replace %clang with a script that run the compiler, upload the result to
the device, and replaces it with another script. The second script runs the
binary on the device and delivers stdout/stderr/exitcode back.

tsan: relax check for errno spoiling more
...
We do not detect errno spoiling for SIGTERM,
because some SIGTERM handlers do spoil errno but reraise SIGTERM,
tsan reports false positive in such case.
It's difficult to properly detect this situation (reraise),
because in async signal processing case (when handler is called directly
from rtl_generic_sighandler) we have not yet received the reraised
signal; and it looks too fragile to intercept all ways to reraise a signal.

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] Enable replacement new/delete on Android.

New/delete implementations in system libraries almost always are built without
frame pointers. As we switched to frame pointer based unwinder on ARM, they no
longer work for us, resulting in broken allocation/deallocation stacks.
Note that this does not work with statically linked
libstdc++/libc++/libstlport.

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
(train data, comparing asan with asan-coverage={0,1,2}):

This change allows to compile sanitizer sources so that *san runtime

all tests from ASan test suite work.

This change adds ASAN_OPTIONS=start_deactivated=1 flag. When present, ASan will

trace gathering, and minimal redzones. All this features come back when
__asan_init is called for the constructor of an instrumented library.
The primary use case for this feature is Android. Code itself is not
Android-specific, and this patch includes a Linux test for it.

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.
