Eli Friedman 4ef077a072 Fix regression from r190427.

Eli Friedman 5a722e92af Add self-comparison warnings for fields.
This expands very slightly what -Wtautological-compare considers to be
tautological to include implicit accesses to C++ fields and ObjC ivars.
I don't want to turn this into a full expression-identity check, but
these additions seem pretty well-contained, and maintain the theme
of checking for "x == x".

Fariborz Jahanian 8181caa44e ObjectiveC [Sema]. This patch makes sure that all inherited
properties (direct or indirect) setter/getter (or declared 
methods as well) are seen by the method implementation type 
matching logic before declaration of method in super class 
is seen. This fixes the warning coming out of that method mismatch.

Richard Smith d7293d7fcb Implement C++'s restrictions on the type of an expression passed to a vararg
function: it can't be 'void' and it can't be an initializer list. We give a
hard error for these rather than treating them as undefined behavior (we can
and probably should do the same for non-POD types in C++11, but as of this
change we don't).

Slightly rework the checking of variadic arguments in a function with a format
attribute to ensure that certain kinds of format string problem (non-literal
string, too many/too few arguments, ...) don't suppress this error.

Eli Friedman 75807f239e Make IgnoreParens() look through ChooseExprs.
This is the same way GenericSelectionExpr works, and it's generally a
more consistent approach.

A large part of this patch is devoted to caching the value of the condition
of a ChooseExpr; it's needed to avoid threading an ASTContext into
IgnoreParens().

Fixes <rdar://problem/14438917>.

Jean-Daniel Dupas 06028a5454 Fix another place where clang check objc selector name instead of checking the selector family
Summary: In ARC mode, clang emits a warning if the result of an 'init' method is unused but miss cases where the method does not follows the Cocoa naming convention but is properly declared as an init family method.

-performSelector: and friends return a value that is boxed as an Objective-C

Some clients may wish to silence this warning based on calling
this method.
