copy the source buffers provided rather than referencing them
directly, so that the caller can free those buffers immediately after
calling clang_createTranslationUnitFromSourceFile(). Otherwise, we
risk hitting those buffers later (when building source ranges, forming
diagnostics, etc.).

This is the way I would like to move the frontend function towards -- distinct
pieces of functionality should be exposed only via FrontendAction
implementations which have clean and relatively-stable APIs.
This also isolates the surface area in clang which depends on LLVM CodeGen.

fixing up a few callers that thought they were propagating NoReturn
information but were in fact saying something about exception
specifications.

to initializer expressions in an array allocated using ASTContext.
This plugs a memory leak when ASTContext uses a BumpPtrAllocator to
allocate memory for AST nodes.
In my mind this isn't an ideal solution; it would be nice to have
a general "vector"-like class that allocates memory using ASTContext,
but whose guts could be separated from the methods of InitListExpr
itself. I haven't gone and taken this approach yet because it isn't
clear yet if we'll eventually want an alternate solution for recylcing
memory using by InitListExprs as we are constructing the ASTs.

we attach diagnostics to translation units and code-completion
results, so they can be queried at any time.
To facilitate this, the new StoredDiagnostic class stores a diagnostic
in a serializable/deserializable form, and ASTUnit knows how to
capture diagnostics in this stored form. CIndex's CXDiagnostic is a
thin wrapper around StoredDiagnostic, providing a C interface to
stored or de-serialized diagnostics.
I've XFAIL'd one test case temporarily, because currently we end up
storing diagnostics in an ASTUnit that's never returned to the user
(because it contains errors). I'll introduce a temporary fix for this
soon; the real fix will be to allow us to return and query invalid ASTs.

why they're getting them:

of operating on each code decl. This exposes two flaws in AnalysisConsumer
that should eventually be fixed:
(1) It is not possible to associate multiple "actions" with a single
command line argument. This will require the notion of an
"analysis" group, and possibly tablegen support. (although eventually
we want to support dynamically loading analyses as well)
(2) AnalysisConsumer may not actually be scanning the declarations in namespaces.
We'll experiment first in LLVMConventionsChecker before changing the
behavior in AnalysisConsumer.

Currently these checks are intended to be largely syntactical, but may get more
sophisticated over time.
As an initial foray into this brave new world, emit a static analyzer warning
when binding a temporary 'std::string' to an 'llvm::StringRef' where the
lifetime of the 'std::string' does not outlive the 'llvm::StringRef'.
