Daniel Dunbar 3d45e17d15 Driver: Add a Tool::hasGoodDiagnostics hook, and use it to simplify logic for 
deciding when we need to emit an extra "command failed" diagnostic.
 - This also fixes the case where we were emitting that extra diagnostics, even
   when using clang w/ the integrated assembler, which has good diagnostics.

Chandler Carruth 8455924303 Add very limited support for GCC's '-B' flag. This allows us to support unusual 
toolchain configurations and is a small step toward FreeBSD support.

Blaine Garst 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.

John McCall 8517abc30d Enable -mconstructor-aliases by default on non-darwin platforms. 
The linker bug holding this back is Darwin-specific.

Daniel Dunbar 0ac9445098 PR5803: clang++: Treat untyped 'C' inputs as C++. 
- Patch by Andrzej K. Haczewski, with a tweak by me to emit a 'deprecated'
   diagnostic when we do this. We'll see what zee users say.

John McCall 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.

Daniel Dunbar 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,
for Darwin ARM.

Daniel Dunbar 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! :)

Daniel Dunbar ffa70e8b27 Driver/Darwin: Don't error/warn on conflicting deployment targets. Apparently 
this is still a popular thing to do.

Benjamin Kramer 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.

Daniel Dunbar 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.
