with multiplication by constants distributed through, occasionally
those subexpressions can include both x and -x. For now, if this
condition is discovered within LSR, just prune such cases away,
as they won't be profitable. This fixes a "zero allocated in a
base register" assertion failure.

This avoids a use-before-def situation in a testcase extracted

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'.

(1) Since CXXMethodDecl subclasses FunctionDecl (and CXXDestructorDecl 
and CXXConversion subclass CXXMethodDecl), refactor switch statement 
to handle them all in one spot.

(2) Use 'DeclarationName::getAsString()' to handle all functions that
don't have simple identifiers (fixing a null dereference when scanning
for specific functions).

see it. Instead, translate the locations up-front when we create a
CXSourceRange.
 - This is part of a move to make CXSourceRange a pure half-open range, which is
   a more natural API for clients to deal with. More cleanups to follow.
