initial support for ObjC exceptions with the GNU runtime:
...
"This patch is a first pass at adding support for exceptions for the GNU runtime. There are a few limitations at present:
- @synchronized() is not yet supported at all. gcc currently emits calls to runtime library functions that don't exist for this directive.
- Only id @catch statements are currently working. This is enough for NS_DURING and friends, but I need to spend more time reading the output from gcc -S to work out how it finds the class pointer to make arbitrary class type catch statements work.
- I've tested it with a few common cases[1] and the clang test suite (which doesn't test exceptions for the GNU runtime, but shows I haven't broken anything else), but there are probably a lot of cases I've missed."

Improve handling of (X86) target features.
...
- 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.

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.
