Added the following custom wrappers:
strstr
strrchr
memchr
nanosleep
socketpair
Tweaked a couple of existing wrappers: if a wrapper returns a pointers derived
from an input pointer, then return the label of the input pointer

This code is not robust enough and triggers when simply linking with
libdynamorio.so, without any code translation at all. Disabling it is safe
(i.e. we may unpoison too much memory and see false negatives, but never false
positives).

It conflicted with the verbosity flag we had in common flags. We don't need an
LSan-specific flag anyway.
Also, shift some logging levels and remove some unnecessary code.
llvm-svn: 197512
Introduce a flag to either always or never print matched suppressions.
Previously, matched suppressions were printed unconditionally if there were
unsuppressed leaks. Also, verbosity=1 no longer has the semantics of "always
print suppressions and summary".
llvm-svn: 197510
Add an interface for telling LSan that a region of memory is to be treated as a
source of live pointers. Useful for code which stores pointers in mapped memory.

*h_errno is written not on success, but on failure.
In fact, it seems like it can be written even when return value signals
success, so we just unpoison it in all cases.

We need to filter out architectures that the compiler hasn't been built to
target (most likely the ARM ones) before attemptint to build a version of
libcompiler_rt.
This can result in a completely empty library (e.g. soft-float doesn't have any
x86 variants), in which case we shouldn't even try the build

Before we did it lazily on the first stack unwind in the thread.
It resulted in deadlock when the unwind was caused by memory allocation
inside pthread_getattr_np:
pthread_getattr_np <<< not reentable
GetThreadStackTopAndBottom
__interceptor_realloc
pthread_getattr_np

it to the LLVM project through the appropriate channels.
This reverts:
r195837: "[Sanitizer] Add rudimentary support for using libbacktrace in ..."

by their authors.
This may break builds where others added code relying on these patches,
but please *do not* revert this commit. Instead, we will prepare patches
which fix the failures.
Reverts the following commits:
r168306: "[asan] support x32 mode in the fast stack unwinder. Patch by H.J. Lu"
r168356: "[asan] more support for powerpc, patch by Peter Bergner"
r196489: "[sanitizer] fix the ppc32 build (patch by Jakub Jelinek)"
llvm-svn: 196802
Summary:
No more (potenital) false negatives due to red zones or fake stack
frames.
