changed the return type of a compare of two unsigned vectors to be unsigned. This patch removes the check for hasIntegerRepresentation since its not needed and returns the appropriate signed type.
I added a new test case and updated exisiting test cases that assumed an unsigned result.

as part of the hash rather than ignoring them. This means we'll end up
building more module variants (overall), but it allows configuration
macros such as NDEBUG to work so long as they're specified via command
line. More to come in this space.

This also applies to C99-style aggregate literals, should they be used in C++11, since they are effectively identical to constructor call list-initialization syntax.

formatting as any other diagnostic, they will be properly line wrapped and
otherwise pretty printed. Let's take advantage of that and the new factoring to
add some helpful information to them (much like template backtrace notes and
other notes): the name of the macro whose expansion is being noted. This makes
a world of difference if caret diagnostics are disabled, making the expansion
notes actually useful in this case. It also helps ensure that in edge cases the
information the user needs is present. Consider:
% nl -ba t5.cc
1 #define M(x, y, z) \
2 y
3
4 M(
5 1,
6 2,
7 3);
We now produce:
% ./bin/clang -fsyntax-only t5.cc
t5.cc:6:3: error: expected unqualified-id
2,
^
t5.cc:2:3: note: expanded from macro: M
y
^
1 error generated.
Without the added information in the note, the name of the macro being expanded
would never be shown.
This also deletes a FIXME to use the diagnostic formatting. It's not yet clear
to me that we *can* do this reasonably, and the production of this message was
my primary goal here anyways.
I'd love any comments or suggestions on improving these notes, their wording,
etc. Currently, I need to make them provide more helpful information in the
presence of a token-pasting buffer, and I'm pondering adding something along
the lines of "expanded from argument N of macro: ...".

standing deficiency: we were providing no macro backtrace information
whenever caret diagnostics were turned off. This sinks the logic for
suppressing the code snippet and caret to the code that actually prints
tho code snippet and caret. Along the way, clean up the naming of
functions, remove some now fixed FIXMEs, and generally improve the
wording and logic of this process.
Add a test case exerecising this functionality. It is notable that the
resulting messages are extremely low quality. I'm working on a follow-up
patch that should address this and have left a FIXME in the test case.

the important code in this test to make the test more stable. Now adding
further tests won't shift the line numbers occuring in the diagnostic
output.

This also adds a -Wc++98-compat-pedantic for warning on constructs which would
be diagnosed by -std=c++98 -pedantic (that is, it warns even on C++11 features
which we enable by default, with no warning, in C++98 mode).

through varargs. This only happens when we're in an unevaluated
context, where we don't want to trigger an error anyway. Fixes PR11131

There are now separate Triple::MacOSX and Triple::IOS values for the OS
so comparing against Triple::Darwin will fail to match those. Note that
I changed the expected output for the Driver/rewrite-objc.m test, which had
previously not been passing Darwin-specific options with the macosx triple.
