[sanitizer] introduce LargeMmapAllocator::GetBlockBeginFastSingleThreaded, required for LeakSanitizer to work faster. Also fix lint.

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.

[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Also fix wrong alignment maths and an outdated comment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.

Introduce a new object library, RTSanitizerCommonLibc, which will contain
the subset of sanitizer_common with libc dependencies. RTSanitizerCommon
contains the remainder of sanitizer_common, and is intended to have no
libc dependencies. Begin moving code to RTSanitizerCommonLibc, starting
with sanitizer_common.cc, whose libc-dependent portion is moved to
sanitizer_common_libcdep.cc, the first member of the new library.

This split affects the CMake build only.  The makefile build continues
to produce the full sanitizer_common library.

[ASan] Make the regression test for time(NULL) Linux-specific, as it crashes on Darwin (and the problem used to occur on Linux).
Do not use zero-based shadow for the time() test.
