Kevin Enderby e1a12cf3ee Fixed a crash in llvm-mc for Mach-O when a symbol difference expression uses a 
symbol from an assignment.  In this case the symbol did not have a fragment so
MCObjectWriter::IsSymbolRefDifferenceFullyResolved() should not have been
calling IsSymbolRefDifferenceFullyResolvedImpl() with a NULL fragment and should
just have returned false in that case.

Bob Wilson aa30aff4f7 Add Triple::getMacOSXVersion to replace crufty code in the clang driver. 
This new function provides a way to get the Mac OS X version number from
either generic "darwin" triples of macosx triples.

Douglas Gregor 232e3431e2 Split compiler builtin module into "stdlib" builtins and "intrinsic" 
builds, and bring mm_alloc.h into the fold. Start playing some tricks
with these builtin modules to mirror the include_next tricks that the
headers already perform.

Bob Wilson 9d3f7af8c3 Fix more fallout from the introduction of "macosx" and "ios" triples. 
The Darwin toolchain constructor was assuming that all Darwin triples would
have an OS string starting with "darwin".  Triples starting with "macosx"
would misinterpret the version number, and "ios" triples would completely
miss the version number (or worse) because the OS name is not 6 characters
long.  We lose some sanity checking of triple strings here, since the
Triple.getOSVersion function doesn't do all the checking that the previous
code did, but this still seems like a step in the right direction.

Howard Hinnant 310fcc749d Back the optimization down from -O3 to -Os. I'm getting an unexplained crasher on -O3. I've looked for a libc++abi bug and can't find one. I'm suspecting clang optimizer bug. But I don't have a good test case at the moment. Deferring investigation on this for now as I will soon be developing more and smaller tests.

Howard Hinnant 3d97931a86 Drop the stress a notch on dynamic_cast_stress.cpp. Otherwise it occasionally causes clang to crash. Put a noexcept(false) on a throwing destructor in test_vector1.cpp. The test now passes for both C++03 and C++11 modes. Add testit script. All tests are now PASSING :-)

Manuel Klimek 31becd7c88 RefCountedBaseVPTR needs the IntrusiveRefCntPtrInfo as friend, 
now that this handles the release / retain calls.

Adds a regression test for that bug (which is a compile-time
regression) and for the last two changes to the IntrusiveRefCntPtr,
especially tests for the memory leak due to copy construction of the
ref-counted object and ensuring that the traits are used for release /
retain calls.
