 - 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.

This CastRegion() performs casts according to the kind of the region being

   --analyze so that it is less automatic (i.e., does not force plist

Fix rdar://6849429 - -Wunused-value with deeply nested macro expansion generates untraceable warnings

The "instantiated from" messages coming from the caret diagnostics system are 
basically walking the macro expansion tree, emitting each level as it goes.  However, it was
skipping certain leaves in the tree by skipping up the entire instantiation arm every time
it went up one spelling arm.  This caused it to miss some things.  For example, in this
testcase:

#define M1(x) x
#define M2 1;

void foo() {
 M1(M2)
}

we now print:

/Users/sabre/Desktop/clang-unused-value-macro.c:6:2: warning: expression result unused

 M1(M2)
 ^~~~~~
/Users/sabre/Desktop/clang-unused-value-macro.c:6:5: note: instantiated from:

 M1(M2)
    ^~
/Users/sabre/Desktop/clang-unused-value-macro.c:3:12: note: instantiated from:

#define M2 1;
           ^

Previously we didn't print the last line, so we never emitted the caret pointing to the 1!

Incidentally, the spaces between the lines is really noisy, I think we should reconsider
this heuristic (which adds them when the printed code starts too close to the start of the
line).

The regression test can't use -verify, because -verify doesn't catch notes for macro
instantiation history.
