(As per one test case, the existing checker thought that this could
cause a lot of false positives - not sure if that's valid, to be
verified.)

Resolves a common false positive, where we were reporting a leak inside
asserts

We use the same logic here as the RetainRelease checker.

Very simple so far - we just highlight every allocation and release
site.

which allows values to escape through unknown calls.

Assumes all calls but the malloc family are unknown.

Also, catch a use-after-free when a pointer is passed to a
function after a call to free (previously, you had to explicitly
dereference the pointer value).

optimistic.

TODO: actually implement the pessimistic version of the checker. Ex: it
needs to assume that any function that takes a pointer might free it.

The optimistic version relies on annotations to tell us which functions
can free the pointer.

post visit of CallExpr.

In general, we should avoid using evalCall as it leads to interference
with other checkers.

Change PathDiagnosticPieces to be reference counted (simplifying their management), and introduce 'PathPieces' as a common container for PathDiagnosticPieces.

Revert my patches which removed Diagnostic.h includes by moving some operator overloads out of line.

This seems to negatively affect compile time onsome ObjC tests
(which use a lot of partial diagnostics I assume). I have to come
up with a way to keep them inline without including Diagnostic.h
everywhere. Now adding a new diagnostic requires a full rebuild
of e.g. the static analyzer which doesn't even use those diagnostics.

This reverts commit 6496bd10dc3a6d5e3266348f08b6e35f8184bc99.

  - Capturing variables by-reference and by-copy within a lambda
  - The representation of lambda captures
  - The creation of the non-static data members in the lambda class
  that store the captured variables
  - The initialization of the non-static data members from the
  captured variables
  - Pretty-printing lambda expressions

There are a number of FIXMEs, both explicit and implied, including:
  - Creating a field for a capture of 'this'
  - Improved diagnostics for initialization failures when capturing
  variables by copy
  - Dealing with temporaries created during said initialization
  - Template instantiation
  - AST (de-)serialization
  - Binding and returning the lambda expression; turning it into a
  proper temporary
  - Lots and lots of semantic constraints
  - Parameter pack captures

Fix all the transitive include users.

- Move the offending methods out of line and fix transitive includers.
- This required changing an enum in the PPCallback API into an unsigned.

llvm-svn: 149782

Fix all the files that depended on transitive includes of Diagnostic.h.
With this patch in place changing a diagnostic no longer requires a full rebuild of the StaticAnalyzer.

Check if the triple OS is IOS instead of checking for arm/thumb architectures
