This CL enables thread support in LSan when used on top of ASan.

In this CL all old tests are removed and one LIT test is added.

Now compiler-rt tests run correctly if compiler-rt is checked out into
arbitrary directory (not necessarily projects/compiler-rt).
Patch by Greg Fitzgerald!

We don't want to report initialization-order bugs when a destructor of a global
variable accesses dynamically initialized global from another
(not necessarily initialized) module. We do this by intercepting __cxa_atexit and
registrering our own callback that unpoisons shadow for all dynamically initialized
global variables.

[ASan] Rename __asan_preinit to __local_asan_preinit to avoid warnings from the linker which is trying to export all the __asan_* symbols

[asan] attempting to fix the debian bot (on ubuntu the test builds; on debian it complains that _SC_PAGESIZE is unknown)

llvm-svn: 182462

[asan] fix dlclose-test to work with non-4K pages. Properly disable interface_symbols_linux on non-x86

llvm-svn: 182461

[asan] workaround for asan bug 189 (swapcontext followed by throw gets OOM kill). Also, disable swapcontext_test on non-x86. Fix lint

llvm-svn: 182456

Keeps it consistent between ASan and LSan.

Also, define CAN_SANITIZE_LEAKS.

[ASan] Don't run fast unwinder tests on 32-bit Linux as fast unwinder may be unexpectedly smart on some hosts

We need this to avoid races when ASan and LSan are used together.

llvm-svn: 182252

Also fix wrong alignment maths and an outdated comment

[sanitizer] factor out ByteMap from SizeClassAllocator32 so that it can be later replaced with a more memory-efficient implementation on 64-bit.

Before, we had an unused internal_getpid function for Linux, and a
platform-independent GetPid function.  To make the naming conventions
consistent for syscall-like functions, the GetPid syscall wrapper
in sanitizer_posix.cc is moved to sanitizer_mac.cc, and GetPid is
renamed to internal_getpid, bringing the Linux variant into use.
