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.

[libsanitizer] Create SanitizerCommonDecorator which provides the Warning() and EndWarning() methods
(needed for SEGV handling in sanitizer_common)

[sanitizer] replace MostSignificantSetBitIndex with LeastSignificantSetBitIndex in bit vector (to iterate bits in increasing order)

Android headers define clone() as a 4-argument function without ellipsis.

llvm-svn: 201331

Fixes AddressSanitizer.SignalTest breakage.

llvm-svn: 201330

Seems stable enough.
Fixes null_deref.cc test.

llvm-svn: 201326

This will be covered by null_deref.cc test (requires one more fix to pass).

With zero base shadow, shadow for near-zero access is itself at near-zero
location. As a result, this test crashes on the shadow access, and not on the
app access.

Relax a check to match this behavior.

It's not always true: on Android, strerror_r with invalid errno
prints "Unknown error ..." to the buffer and returns 0.

This test now only checks that strerror_r does not crash.

[sanitizer] more code for deadlock detector, nothing really works yet (except for small unit tests).

llvm-svn: 201302

Also, fix incorrect syscall hooks for the corresponding syscalls.

llvm-svn: 201252

llvm-svn: 201240

It's called __wait4 there.

llvm-svn: 201235

[sanitizer] added class BVGraph, to be used in a deadlock detector; added more methods to the bit vectors

[Sanitizer] Teach external symbolizer to work with addr2line if llvm-symbolizer is unavailable. Allow this mode in TSan.

Because of the way Bionic sets up signal stack frames, libc unwinder is unable
to step through it, resulting in broken SEGV stack traces.

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

llvm-svn: 201151

llvm-symbolizer binary and external process handling into separate classes.

No functionality change.
