Also added a test case for runtime error reporting.

Summary:
Fix import from module with appending var, which cannot be imported. The
first fix is to remove an overly-aggressive error check.

The second fix is to deal with restructuring introduced to the module
linker yesterday in r254418 (actually, this fix was included already
in r254559, just added some additional cleanup).

Test by Mehdi Amini.

After, properties from class extensions no longer show up in
ObjCInterfaceDecl::properties().  Make ObjCCommonMac::EmitPropertyList()
explicitly look for properties in class extensions before looking at
direct properties.

Also add a test that passes both with clang before r251874 and after this
patch (but fails with r251874 and without this patch).

`MaybeReexec` contains a 1024-byte long local array, which produces a warning about frame size:

   .../lib/sanitizer_common/sanitizer_mac.cc:548:6: warning: stack frame size of 1132 bytes in function '__sanitizer::MaybeReexec' [-Wframe-larger-than=]

For OS X builds of compiler-rt, we run `darwin_test_archs` to determine which architectures can the toolchain target. This detection takes quite a long time, and the result is always the same (as long as you don't upgrade your OS, system headers or toolchain). Let's cache the result.

Currently "<type> ptr <reg name>" treated as <reg name> in MS inline asm, ignoring the "<type> ptr" completely and possibly ignoring the intention of the user.
Fixed llvm to produce an error when encountering "<type> ptr <reg name>" operands.

For example: andpd xmm1,xmmword ptr xmm1 --> andpd xmm1, xmm1 
though andpd has 2 possible matching formats - andpd xmm, xmm/m128

Previously we used sys.os.path for appending target pathes what failed
when cased dlopen to fail on the target because of the '\'.

The fix won't work for local Windows tests but dlopen don't available
on Windows anyway so the test don't make sense in that context.

In AddressSanitizer, we have the MaybeReexec method to detect when we're running without DYLD_INSERT_LIBRARIES (in which case interceptors don't work) and re-execute with the environment variable set. On OS X 10.11+, this is no longer necessary, but to have ThreadSanitizer supported on older versions of OS X, let's use the same method as well. This patch moves the implementation from `asan/` into `sanitizer_common/`.

This CL is for discussion how to better fix bit-filed layout compatibility issue with GCC (see PR25575 for test case and more details). Current clang behavior is compatible with GCC 4.1-4.3 series but it was fixed in 4.4+. Ignoring packed attribute looks very odd and because it was also fixed in GCC 4.4+, it makes sense also fix it in clang.
