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

[sanitizer] fix asan on the platforms where the page size is not a compile-time constant (or at least where EXEC_PAGESIZE may not be trustworthy), e.g. powerpc64. 

llvm-svn: 182351

GetPageSize wraps sysconf(_SC_PAGESIZE) on POSIX platforms, but
sysconf resides in libc.  To make this libc-independent on Linux,
move the wrapper to sanitizer_mac.cc and return the Linux-specific
constant EXEC_PAGESIZE in the sanitizer_linux.cc implementation.

__libc_stack_end is made into a weak symbol if possible.  If libc is
not linked, read args and environment from /proc.

Add missing call to GetUserBegin().

[libsanitizer] Introduce INTERCEPTOR_WITH_SUFFIX which is to be used for appending the __DARWIN_ALIAS() version suffixes to function names on Darwin.
This should fix asan/lit_tests/wait.cc under ASan.

Separate the notions of user-visible chunk and allocator chunk, to facilitate
ASan integration.

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