Introduce Decl::hasBody() and FunctionDecl::hasBody() and use them instead of getBody() when we are just checking the existence of a body, to avoid de-serialization of the body from PCH.

Makes de-serialization of the function body even more "lazier".

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'.
