e46b52a35f Driver: Fix a number of -fapple-kext issues: 
- Disable RTTI.
 - Disable use of __cxa_atexit.
 - Disable unwind tables.
 - Enable freestanding mode.

Also, honor -fhosted correctly.

<rdar://problem/7515383> C++ support: -fapple-kext not honored

fe06df4bf3 C++: Add support for -fno-use-cxa-atexit. 
- So much typing, so little gain...

Also, rename the __cxx_global_initialization function just to match llvm-gcc.

fc83aa04db Unconditionally support block introspection data in a new field at the end 
of the block descriptor field.  This field is the ObjC style @encode
signature of the implementation function, and was to this point
conditionally provided in the block literal data structure.  That
provisional support is removed.

Additionally, eliminate unused enumerations for the block literal flags field.
The first shipping ABI unconditionally set (1<<29) but this bit is unused
by the runtime, so the second ABI will unconditionally have (1<<30) set so
that the runtime can in fact distinguish whether the additional data is
present or not.

bb79b5f6f3 Raise the responsibility for passing -disable-llvm-verifier in NDEBUG builds 
to the driver, and support it in CodeGenOptsToArgs().  Note that this changes
the default behavior of clang -cc1 to always run the verifier.

3241d400c8 Switch to using -fsjlj-exceptions instead of hard-coding it. Notably, this fixes 
calls to the UnwindResumeOrRethrow function for C++/Obj-C exception handling,

c434394d18 Driver: Add -[no-]integrated-as for clang. 
- Requires backend support, which only exists for i386--darwin currently.

No 'as' required:
--
ddunbar@ozzy:tmp$ cat t.c
int main() { return 42; }
ddunbar@ozzy:tmp$ clang -m32 -integrated-as t.c


ddunbar@ozzy:tmp$ ./a.out; echo $?
42
ddunbar@ozzy:tmp$
--

The random extra whitespace is how you know its working! :)

842bf17366 Use StringRef instead of returning a temporary std::string. 
This fixes a really nasty bug in Darwin::getDarwinArchName where we were going
StringRef -> temporary std::string -> StringRef (and return the dead StringRef).
The StringRefs from Triple live as long as the Triple itself, that should be
long enough.

Hopefully 2 of 4 MSVC buildbot failures are gone now.

1299819f71 Driver: Don't honor -std-default for C++, this makes it hard to run the gdb test 
suite with clang++ enabled.

The right fix here is PR6175, although we would still have to find a different
work around for the gdb test suite.

ac0605e927 Introduce serialization and deserialization of diagnostic information 
so that CIndex can report diagnostics through the normal mechanisms
even when executing Clang in a separate process. This applies both
when performing code completion and when using ASTs as an intermediary
for clang_createTranslationUnitFromSourceFile().

The serialized format is not perfect at the moment, because it does
not encapsulate macro-instantiation information. Instead, it maps all
source locations back to the instantiation location. However, it does
maintain source-range and fix-it information. To get perfect fidelity
from the serialized format would require serializing a large chunk of
the source manager; at present, it isn't clear if this code will live
long enough for that to matter.
