Chandler Carruth 45c2fb1e69 Undo part of my previous commit to mm_malloc.h, going back to the use of
stdlib.h. There were numerous problems with forward declaring 'malloc' and
'free', but the most important is that these are reserved by POSIX and may be
implemented via a function-like macro.

As suggested by Dale Johannesen, I'm instead guarding the only include of this
in our builtin headers with __STDC_HOSTED__, and I've removed the include of
the header from the test suite. I'll discuss with folks whether we want to have
a hosted section of the test suite or not, and add it (and perhaps other tests)
back there if that's the direction.

John McCall 7decc9e4ea Calculate the value kind of an expression when it's created and
store it on the expression node.  Also store an "object kind",
which distinguishes ordinary "addressed" l-values (like
variable references and pointer dereferences) and bitfield,
@property, and vector-component l-values.

Currently we're not using these for much, but I aim to switch
pretty much everything calculating l-valueness over to them.
For now they shouldn't necessarily be trusted.

Argyrios Kyrtzidis 14a96625b8 Don't warn for parentheses for the '&&' inside '||' for cases like:
assert(a || b && "bad");

since this is safe. This way we avoid a big source of such warnings which in this case are practically useless.

Note that we don't handle *all* cases where precedence wouldn't matter because of constants since
this is a bit costly to check, and IMO clarifying precedence with parentheses is good for
readability in general.

Douglas Gregor 30313cbb80 When libclang is walking a member access expression, don't walk into
an implicit "this"; it causes clang_getCursor() to find the implicit
"this" expression (which isn't written in the source!) rather than the
actual member.

interest (e.g., as used by clang_getCursor()), count the
decl-specifier-seq as part of the source range, as we do for
clang_annotateTokens(). Makes clang_getCursor() work properly for the
result types of functions, for example.

Bob Wilson db04141f9a Re-enable test with modifications for Neon vector changes in clang.
I mistakenly thought that this was checking for vector name mangling, but
it is not.  Since we're no longer wrapping Neon vectors in structs, this
test can just return a vector directly.  There are already other tests for
that, so just to make this interesting, change the test to return a struct
of two vectors.

Douglas Gregor 68dbaead7b Fix source-range information for Objective-C properties. Previously,
we were just getting a range covering only the property name, which is
certainly not correct (and broke token annotation, among other
things). 

Also, teach libclang about the relationship between
@synthesize/@dynamic and @property, so we get property name and
cursor-reference information for @synthesize and @dynamic.

John McCall 07bb19667a Simplify some complex emission and implement correct semantics for
assignment to volatiles in C.  This in effect reverts some of mjs's
work in and around r72572.  Basically, the C++ standard is quite
clear, except that it lies about volatile behavior approximating
C's, whereas the C standard is almost actively misleading.

Chandler Carruth 1c8383dccd Fix PR8625 and correctly interpret member-calls to static members when
producing warnings.

This feels really fragile, and I've not audited all other argument index-based
warnings. I suspect we'll grow this bug on another warning eventually. It might
be nice to adjust the argument indices when building up the attribute AST node,
as we already have to remember about the 'this' argument within that code to
produce correct errors.

Chandler Carruth 743682bb9f Re-work the handling of implicit 'this' arguments and silly GCC-style attribute
argument indexes. This handles the offsets in a consistent manner for all of
the attributes which I saw working with these concepts. I've also added tests
for the attribute that motivated this: nonnull.

I consolidated the tests for format attributes into one file, and fleshed them
out a bit to trigger more of the warning cases. Also improved the quality of
some of the diagnostics that occur with invalid argument indices.

The only really questionable change here is supporting the implicit this
argument for the ownership attribute. I'm not sure it's really a sensible
concept there, but implemented the logic for consistency.

Douglas Gregor ee430a39c3 Implement C++0x [temp.func.order]p3 (aka DR532) properly. In
particular, we only add the implement object parameter type if only
one of the function templates is a non-static member function
template.

Moreover, since this DR differs from existing practice in C++98/03,
this commit implements the existing practice (which ignores the
first parameter of the function template that is not the non-static
member function template) in C++98/03 mode.
