eb931c6b0e The ASTReader created by -chain-include used the generated PCH buffers in the wrong order. The effect was that all but the first chain-include files was ignored for subsequent compilations.

6620ddeaa4 Re-fix r129481 and r129465 properly. Nulls fixits shouldn't be dropped in 
DiagnosticBuilder::AddFixItHint: they will be dropped along with any
other (possibly valid) fixits later.

36e4ae3e57 When creating an implicit member expression through a qualified-id, check that the class 
named by the nested-name-specifier is same or base of the class in which the member expression appears.

It seems we also had an ill-formed test case, mon dieu! Fixes rdar://8576107.

d162fb83f2 In C++, when initializing an array from a pascal string, it's OK if the array 
is 1 element smaller than the string, because we can just strip off the last
null character. This matches GCC.

0a7aa3b60b Teach -Wuninitialized about C++'s typeid expression, including both the 
evaluated and unevaluated contexts. Add some testing of sizeof and
typeid.

Both of the typeid tests added here were triggering warnings previously.
Now the one false positive is suppressed without suppressing the warning
on actually buggy code.

b9c9e34cb3 Just use a native "load" instead of translating the builtin later. Clang can 
take it!

I wasn't able to get __builtin_ia32_loaddqu to transform into an unaligned
load...I'll have to look into it further.

48c946e5ef In Microsoft mode, within class scope, if a CXXScopeSpec's type is equal to the type of one of the base classes then downgrade the missing typename error to a warning. Up to now this is the only case I found where MSVC doesn't require "typename" at class scope. Really strange! 
This fixes 1 error when parsing the MSVC 2008 header files.
Example:

template<class T> class A {
public:
  typedef int TYPE;
};
template<class T> class B : public A<T> {
public:
  A<T>::TYPE a; // no typename required because A<T> is a base class.
};

9c8cd4c097 IRgen/Obj-C: Emit CFStrings and NSStrings with the alignment of the char type, 
there is no reason to align them higher.
 - This roughly matches llvm-gcc's r126913.
 - It is an open question whether or not we should do this for cstring's in
   general (code size vs optimization potential), for now we just match llvm-gcc
   until someone wants to run some experiments.

58989b7125 We can't emit an aggregate cast as its sub-expression in general just 
because the result is ignored.  The particular example here is with
property l-values, but there could be all sorts of lovely casts that this
isn't safe for.  Sink the check into the one case that seems to actually
be capable of honoring this.

2979fe01da After some discussion with Doug, we decided that it made a lot more sense 
for __unknown_anytype resolution to destructively modify the AST.  So that's
what it does now, which significantly simplifies some of the implementation.
Normal member calls work pretty cleanly now, and I added support for
propagating unknown-ness through &.
