Kostya Serebryany ad272b0861 [asan] fix one more case where stack-use-after-return is not async-signal-safe (during thread startup). beef-up the test to give it a chance to catch regressions. Also relax the lint to make C++11 more usable.

Francis Ricci 81378e46bb [compiler-rt] Allow nm program to be over-ridden for global symbol detection 
Summary:
While cross-compiling, a custom nm program may be required. This will also allow for the
use of llvm-nm if desired.

Sagar Thakur b1c51f6a94 [ASAN] Use struct instead of array in sancov.py 
Summary: When using 32-bit python with 64-bit asan the pc array in sancov.py cannot fit in 64-bit pc's because the type-code 'L' for
arrays in python corresponds to the C type long which is only of 4 bytes. Because of this some of the coverage tool tests fail on
mips. To fix these test possible solutions are to use 64-bit python or use struct.unpack with the 'Q' type-code. We have used
struct.unpack with 'Q' type code since it is not appropriate to have a 64-bit python on all hosts.

Evgeniy Stepanov 567e516015 [asancov] Write coverage directly to a memory-mapped file. 
This way does not require a __sanitizer_cov_dump() call. That's
important on Android, where apps can be killed at arbitrary time.

We write raw PCs to disk instead of module offsets; we also write
memory layout to a separate file. This increases dump size by the
factor of 2 on 64-bit systems.

Sergey Matveev 6cb47a083b [sanitizer] Support sandboxing in sanitizer coverage. 
Summary:
Sandboxed code may now pass additional arguments to
__sanitizer_sandbox_on_notify() to force all coverage data to be dumped to a
single file (the default is one file per module). The user may supply a file or
socket to write to. The latter option can be used to broker out the file writing
functionality. If -1  is passed, we pre-open a file.
