Nadav Rotem d5aae980cb In some cases, due to scheduling constraints we copy the EFLAGS. 
The only way to read the eflags is using push and pop. If we don't
adjust the stack then we run over the first frame index. This is
not something that we want to do, so we have to make sure that
our machine function does not copy the flags. If it does then
we have to emit the prolog that adjusts the stack.

Ted Kremenek 44c2a2a26e Change checkUnsafeAssignLiteral() to use the new Sema::CheckLiteralKind(). 
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.

Sean Callanan 5deaa4c902 Made LLDB compile with LLVM top-of-tree again. 
The results from Clang name lookups changed to
be ArrayRefs, so I had to change the way we

we iterate across results.

Jordan Rose 7b5bfc795a [analyzer] Don't perform an expensive assertion in release builds. 
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.

Anna Zaks 1ee76c1bae [analyzer] Re-apply r170826 and make the dumping of the GallGraph 
deterministic.

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.
