 - We could just warn about -fno-unit-at-a-time, but in practice people using it
   probably aren't going to get what they want out of clang.

Also, use "clang" specified error for unsupported things instead of driver
unsupported error.

 - This commit has some messy stuff in it to extend string lifetimes, but that
   will go away once we switch to using the enum'd Triple interfaces.

 - Default to yonah on Darwin (to get SSE3).

 - This is a WIP...

 - This adds -march= handling to the driver, and fixes the defaulting
   of -mcpu on Darwin (which was using the wrong test).

Instead of handling -m{sse, ...} in the driver, pass them to clang-cc as
 -target-feature [+-]name

In clang-cc, communicate with the (clang) target to discover the legal
features of a target, and the features which are enabled based on
-mcpu. This is currently hardcoded just enough to not be a feature
regression, we need to get this information from the backend's
TableGen information somehow.

This is used to construct the full list of features which are being
used, which is in turn used to initialize the predefines.

 - Currently just an alias for --analyze, eventually we want to refit
   --analyze so that it is less automatic (i.e., does not force plist
   output and does not hard code the list of checks).

 - This implements gcc style Objective-C interface layout (I
   think). Currently it is always off, there is no functionality
   change unless this is passed.
   
   For the curious, the deal is that gcc lays out the fields of a
   subclass as if they were part of the superclass. That is, the
   subclass fields immediately follow the super class fields instead
   of being padded to the alignment of the superclass structure.

 - Currently gcc uses the tight layout in 32-bit and 64-bit modes, and
   llvm-gcc uses it in 32-bit only, for reasons which aren't clear
   yet. We probably want to switch to matching gcc, once this makes it
   through testing... my hope is that we can also fix llvm-gcc in
   order to maintain compatibility between the compilers.

Also, put a line of whitespace between the diagnostic and the source
code/caret line when the start of the actual source code text lines up
(or nearly lines up) with the most recent line of the diagnostic. For
example, here it's okay for the last line of the diagnostic to be
(vertically) next to the source line, because there is horizontal
whitespace to separate them:

decl-expr-ambiguity.cpp:12:16: error: function-style cast to a builtin
      type can only take one argument
  typeof(int)(a,5)<<a;

However, here is a case where we need the vertical separation (since
there is no horizontal separation):

message-length.c:10:46: warning: incompatible pointer types initializing 'void
      (int, float, char, float)', expected 'int (*)(int, float, short,
      float)'

      int (*fp1)(int, float, short, float) = f;
