Threads now store their "temporary" resume state, so we know whether they were suspended in the most
recent step, and if they weren't allowed to run, don't ask questions about their state unless explicitly
requested to do so.

MCObjectWriter::IsSymbolRefDifferenceFullyResolved() should not have been
calling IsSymbolRefDifferenceFullyResolvedImpl() with a NULL fragment and should
just have returned false in that case.

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.

This class is used to represent SubRegIndex instances instead of the raw
Record pointers that were used before.

No functional change intended.

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.

llvm-svn: 149414

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 :-)

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.
