08a2ede018 Add logic for invalidating array region to CFRefCount.cpp. When invalidating
array region, set its default value to conjured symbol. When retrieving its
element, create new region value symbol for the element.

Also fix some 80 columns violations.

45fe0364aa Make precompiled headers work with -E. When we're only preprocessing
(with -E), we turn the PCH include into an implicit include of the
file from which the PCH file was generated.

d002c7bc58 Encapsulate template arguments lists in a new class,
TemplateArgumentList. This avoids the need to pass around
pointer/length pairs of template arguments lists, and will eventually
make it easier to introduce member templates and variadic templates.

c9f9b86732 Implement the notions of the "current instantiation" and "unknown
specialization" within a C++ template, and permit name lookup into the
current instantiation. For example, given:

  template<typename T, typename U>
  struct X {
    typedef T type;

    X* x1;  // current instantiation
    X<T, U> *x2; // current instantiation
    X<U, T> *x3; // not current instantiation
    ::X<type, U> *x4; // current instantiation
    X<typename X<type, U>::type, U>: *x5; // current instantiation
  };

e362cea568 Implement the semantics of the injected-class-name within a class
template. The injected-class-name is either a type or a template,
depending on whether a '<' follows it. As a type, the
injected-class-name's template argument list contains its template
parameters in declaration order.

As part of this, add logic for canonicalizing declarations, and be
sure to canonicalize declarations used in template names and template
arguments. 

A TagType is dependent if the declaration it references is dependent.

I'm not happy about the rather complicated protocol needed to use
ASTContext::getTemplateSpecializationType.

dc04654697 reimplement __sync_* builtins to be variadic and to follow the same
semantic rules that gcc and icc use.  This implements the variadic
and concrete versions as builtins and has sema do the 
disambiguation.  There are probably a bunch of details to finish up
but this seems like a large monotonic step forward :)

bb8d546208 Refactor BugReporter interface to have a new 'BugReporterContext' and
'BugReporterVisitor'. This simplifies callbacks from BugReporter to BugReports
(via VisitNode). It also lays the foundation for arbitrary visitor "call backs"
that can be registered to a BugReporterContext as a PathDiagnostic is
constructed. These call backs can help operate as separate "experts" that can
work on constructed pieces of a PathDiagnostic for which they possess special
knowledge.

bb36aed06b More x86 target feature support.
- Apologies for the extremely gross code duplication, I want to get
   this working and then decide how to get this information out of the
   back end.

 - This replaces -m[no-]sse4[12] by -m[no-]sse4, it appears gcc
   doesn't distinguish them?

 - -msse, etc. now properly disable/enable related features.

 - Don't always define __SSE3__...

 - The main missing functionality bit here is that we don't initialize
   the features based on the CPU for all -march options.

4dbaaa6f43 Improve handling of (X86) target features.
- 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.

   output and does not hard code the list of checks).
