Eric Fiselier 30130f2070 [compiler-rt] Add common interceptor for wcrtomb. 
Summary: Currently there is a libc++ test failing under MSAN because wcrtomb is not intercepted. This patch adds an interceptor for it.

Kostya Serebryany d99f2b3291 [sanitizer] add a weak hook for memcmp interceptor, to be used primarily for fuzzing. More hooks will be added later. So far this is a Linux-only feature

Kostya Serebryany c69bf1b4c0 [asan,tsan,msan] move the memcmp interceptor from asan/tsan to sanitizer_common. This may potentially lead to more reports from msan as it now sees the reads inside memcmp. To disable, use the flag intercept_memcmp=0. Likewise, it may potentially cause new races to appear due to more strict memcmp checking (flag strict_memcmp=1)

Jay Foad 86269dc5d0 [msan] Teach sanitizers about the PPC64 ptrace syscall 
Summary:
This fixes test/msan/Linux/syscalls.cc, and should also fix the ppc64
sanitizer buildbots which are currently failing in
"make check-sanitizer".

Evgeniy Stepanov 4af9c0ea80 [asan] i686-linux-android support. 
Large part of this change is required due to
  https://code.google.com/p/android/issues/detail?id=61799
dlsym() crashes when symbol resolution fails, which means
we have to limit the interceptor list instead of relying on
runtime detection.

There are minor differencies in system headers, too.

Evgeniy Stepanov 360c911872 [asan] Disable dlopen interceptor on Android.

even ahead of LD_PRELOAD-ed libraries.

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.
