Fix a bug in the mangler where in 'namespace std { extern "C" {X;} }', X would not be seen to be in ::std::.

Migrate two other places where the same logic is used to use the helper function that already exists.

-Make sure we don't change to '__weak' a __block variable used as output.
-Make sure we don't apply __weak twice.

Introduce PreprocessingRecord::rangeIntersectsConditionalDirective() which returns
true if a given range intersects with a conditional directive block.

-Add location parameter for the directives callbacks
-Skip callbacks if the directive is inside a skipped range.
-Make sure the directive callbacks are invoked in source order.

Avoid an unnecessary recursive loop between type canonicalization and NNS canonicalization which would (rarely) lead to memory corruption.  While I'm here, simplify.  Fixes PR12166.  Not committing a testcase because it's impossible to reduce it.

[analyzer] do not warn about returning stack-allocated memory when it comes from an ancestor stack frame.

 - This is a more reliable default, as it behaves better on failure and also
   ensures that we create *new* files (instead of reusing existing inodes). This
   is useful for other applications (like lldb) which want to cache inode's to
   know when a file has been rewritten.

Frontend: Don't automatically create missing directories when using temporary files with createOutputFile()
 - This would otherwise happen as a side effect of llvm::sys::fs::unique_file creating parent directories.

This is a preparation to adding an AST-based call graph to Analysis. The
existing call graph works with indexer entries. We might be able to
refactor it to use the AST based graph in the future.

(Minimal testing here as the only example that uses the API has been
completely broken, does not compile.)

ptrdiff_t on PPC32 on Linux, etc. should be int not long.
This does not matter for C, but it does matter for C++ because of
name mangling.

The preprocessor test has been changed accordingly.

This is consistent with -Wbool-conversion. Let me know if you prefer
