Argyrios Kyrtzidis 1cec2cc798 Remove dead code, caught by unused function warnings.

Argyrios Kyrtzidis 36ea322579 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".

Nick Lewycky 6cbc3f7de4 Refactor the Is{Std,Clang,LLVM}Namespace methods and rename 'isClangAttr' to 
'IsClangAttr' to match prevailing style in this file. Patch by Jon Mulder!

Ted Kremenek 4ba99bee2a clang::Attr objects should be treated as AST nodes as well by 
the LLVMConventionsChecker.

Ted Kremenek 4853131459 Add LLVM conventions check that scans for AST elements (types, stmts, decls) 
that allocate heap memory.

Ted Kremenek 988805c81e Change LLVMConventionsChecker to accept an entire translation unit instead 
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.

Ted Kremenek c968e5e9b9 For the StringRef check, also visit the children of DeclStmts.

Ted Kremenek 4806a833a7 Place type-checking static methods at type of file (where they will congregate). 
No functionality change.

Ted Kremenek 184b3383bf Add new static analyzer for checking LLVM coding conventions: -analyzer-check-llvm-conventions 
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'.
