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

[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.

[ASan] Fix allow_user_segv.cc on Darwin (32-bit build required a SIGBUS handler instead of the SIGSEGV one)

[asan] symbolize when possible, even if ASAN_SYMBOLIZER_PATH is not provided. On Linux this will use dl_iterate_phdr instead of /proc/self/maps, even if the symbolizer is not installed

[ASan] Disable strict-init-order checker once we have more than one thread, as this mode is thread-hostile

llvm-svn: 180106

This change adds ASan runtime option "strict-init-order" (off by default)
that makes init-order checker bark if global initializer accesses any global from different
translation unit (even if the latter is already initialized). strict init-order checking
doesn't play well with, e.g. LLVM registration machineries, and causes issue 
https://code.google.com/p/address-sanitizer/issues/detail?id=178.
