Report segmentation faults near or below stack bottom as stack-overflow
(not stack-buffer-overflow!).

Android libc always sets altstack on non-main threads, but it is too small for
our unwinder. With use_sigaltstack=1, override this setting with a larger one.

[CMake] Add top-level target for each compiler-rt library, and add 'compiler-rt' target encompassing them all.

[tsan] rudimentary support for deadlock detector in tsan (nothing really works yet except for a single tiny test). Also rename tsan's DeadlockDetector to InternalDeadlockDetector

llvm-svn: 201407

llvm-svn: 201406

[sanitizer] add iterators to bit vectors; make bit vector operations use little stack; add common flag 'detect_deadlocks'

These are runtime support functions for inline assembly instrumentation.

Patch by Yuri Gorshenin.

This is covered by existing ASan test.
This does not change anything for TSan by default (but provides a flag to 
change the threshold size).
Based on a patch by florent.bruneau here:

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.
