- Default to yonah on Darwin (to get SSE3).
- Default to Pentium4 (32-bit) and x86-64 (64-bit) on
non-Darwin. Welcome to the 21st century.

- 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).

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.

__sync_umin_and_fetch), add some missing atomic builtins (e.g.
__sync_fetch_and_nand) and reorder the list to match the GCC
documentation. The builtins still need work and codegen
implementation, more patches coming.

to go back and clean up existing uses of the bitcasted function. This
is not just an optimization: it is required for correctness to get
always inline functions to work, see testcases in function-attributes.c.

compensating for super classes). This was making the reported class
sizes for empty classes very, very wrong.
- Also, we now report the size info for an empty class like gcc (as
the offset of the start, not as 0, 0).
- Add a few more test cases we were mishandling before (padding bit
field at end of struct, for example).
