Our current inlining support (specifically RegionStore::enterStackFrame)
doesn't know that calls to overloaded operators may be calls to non-static
member functions, and that in these cases the first argument should be
treated as 'this'. This caused incorrect results and sometimes crashes.
The long-term fix will be to rewrite RegionStore::enterStackFrame to use
CallEvent and its subclasses, but for now we can just disable these
problematic calls by classifying them under a new CallEvent,
CXXMemberOperatorCall.

By default on OS X 10.8, we don't link with a crt1.o file and the linker
knows to use _main as the entry point. But, when compiling with -pg, we
need to link with the gcrt1.o file, and the linker needs to be told to use
the "start" symbol as the entry point. The -no_new_main linker option does
that last part. <rdar://problem/11491405>

- Return integer vectors in integer registers.
- Pass vector arguments in integer registers.
- Set an upper bound for argument alignment. The largest alignment is 8-byte
for O32 and 16-byte for N32/64.

I really feel like Clang should warn about this, but I can't describe
a good reason. GCC will warn on this in some cases under
-Wsequence-point, but it actually seems like a false positive for that
warning....

if we want to ignore a result, the Dest will be null. Otherwise,
we must copy into it. This means we need to ensure a slot when
loading from a volatile l-value.
With all that in place, fix a bug with chained assignments into
__block variables of aggregate type where we were losing insight into
the actual source of the value during the second assignment.

given a cursor pointing to a C++ method call or an ObjC message,
returns non-zero if the method/message is "dynamic", meaning:
For a C++ method: the call is virtual.
For an ObjC message: the receiver is an object instance, not 'super' or a
specific class.

* Primarily, added \brief to most of include/clang/Basic, instead of prefixing
the comments with "DeclaredName - ";
* Made some brief summaries significantly briefer;
* Fixed up some erroneous uses of \see and \arg;
* Fixed up some extraneous backslashes in \code...\endcode blocks;
* Fixed up some typos/spelling errors.

* repro script contains macro definitions (-DFOO=BAR).

...and instead add an accessor. We're not using this today, but it's something
that should probably stay in the source for potential clients, and it doesn't
cost a lot. (ObjCPropertyAccess is only created on the stack, and right now
there's only ever one alive at a time.)

Clang unit tests. It's not clear why we support this mode in builds
where LLVM is available (LLVM itself does not), but at least this makes
us support it correctly.
This also fixes a long-standing bug where we would pass the unit test
param flag to lit in the standalone build even though the standalone
build *never* has the unittests built and ready for testing.

Now that we're only using -frewrite-includes rather than full preprocessing
when producing repro source files, we should also include command line macro
definitions in the repro script.
I don't have a test case for this because I'm not sure if/how I can open the
crash report file when the name is only known by scraping the crash report
output. Suggestions welcome if anyone thinks it'd be helpful.

In C, enum constants have the type of the enum's underlying integer type,
rather than the type of the enum. (This is not true in C++.) Thus, when a
block's return type is inferred from an enum constant, it is incompatible
with expressions that return the enum type.
In r158899, I told block returns to pretend that enum constants have enum
type, like in C++. Doug Gregor pointed out that this can break existing code.
Now, we don't check the types of return statements until the end of the block.
This lets us go back and add implicit casts in blocks with mixed enum
constants and enum-typed expressions.

template instantiation. I wasn't able to reproduce this down to
anything small enough to put in our test suite, but it's "obviously"
okay to set the invalid bit earlier and precludes a
known-broken-but-not-marked-broken class from being used elsewhere.

This will likely make the lit runs in Clang much more suitable to IDEs
such as Xcode and MSVC when operating in a standalone mode.
