Following r168626, in class declaration or definition, there are a combination of syntactic locations
where C++11 attributes could appear, and among those the only valid location permitted by standard is
between class-key and class-name. So for those attributes appear at wrong locations, fixit is used to
move them to expected location and we recover by applying them to the class specifier.

Uses of clang_getSpellingLocation should eventually move to calling
clang_getFileLocation, and clang_getSpellingLocation should do what
its name represents and actually point at the 'spelling' location, e.g.
inside a macro definition if the spelling of a token came from that.

This patch moves hasCLanguageLinkage to be VarDecl and FunctionDecl methods
so that they can be used from SemaOverload.cpp and then fixes the logic
in Sema::IsOverload.

Changed getLocStart() and getLocEnd() to be required for Stmts, and make
getSourceRange() optional. The default implementation for getSourceRange()
is build the range by calling getLocStart() and getLocEnd().

the body of a functions. The problem was that hasBody looks at the entire chain
and causes problems to -fvisibility-inlines-hidden if the cache was not
invalidated.
Original message:
Cache visibility of decls.
This unifies the linkage and visibility caching. I first implemented this when
working on pr13844, but the previous fixes removed the performance advantage of
this one.
This is still a step in the right direction for making linkage and visibility
cheap to use.

Apply all formatting changes that clang-format would apply to its own source
code. All choices seem to improve readability (or at least not make it worse).
No functional changes.

This was removed with -Wunique-enum, which is still removed. The
corresponding thread on cfe-comments for that warning is here:
http://lists.cs.uiuc.edu/pipermail/cfe-dev/2012-September/024224.html
If we get specific user feedback for -Wduplicate-enum we can evaluate
whether or not to keep it.

Along the way, fix a bug in CheckLiteralKind(), previously in diagnoseObjCLiteralComparison, where we didn't ignore parentheses
in boxed expressions for purpose of classification.
In other words, both @42 and @(42) should be classified as numeric
literals.

the values in the constructor. The constructor implementation is trivial
beyond the value initialisations. Patch by Saleem Abdulrasool!

Unfortunately, we don't seem to have a standard way to do this. I'm using
the __OPTIMIZE__ GNU extension that Clang also defines, but that doesn't
help MSVC. I suppose we could remove the check entirely, but it's useful
for developing new constraint managers.

Commit message for r170826:
[analyzer] Traverse the Call Graph in topological order.
Modify the call graph by removing the parentless nodes. Instead all
nodes are children of root to ensure they are all reachable. Remove the
tracking of nodes that are "top level" or global. This information is
not used and can be obtained from the Decls stored inside
CallGraphNodes.
Instead of existing ordering hacks, analyze the functions in topological
order over the Call Graph.
Together with the addition of devirtualizable ObjC message sends and
blocks to the call graph, this gives around 6% performance improvement
on several large ObjC benchmarks.

This paves the road for constructing a better function dependency graph.
If we analyze a function before the functions it calls and inlines,
there is more opportunity for optimization.
Note, we add call edges to the called methods that correspond to
function definitions (declarations with bodies).
