Now instead of just tracking the expansion history, also track the full
range of the macro that got replaced.  For object-like macros, this doesn't
change anything.  For _Pragma and function-like macros, this means we track
the locations of the ')'.

This is required for PR3579 because apparently GCC uses the line of the ')'
of a function-like macro as the location to expand __LINE__ to.

Now we are pretty close to be in sync with objc's classic 
abi when it comes to passing dejagnu objc executable tests.

Add -ffreestanding to suppress the implicit declaration of library builtins like printf and malloc. Fixes PR3586

which consequently caused a Seg fault. during meta-data
generation. It also addresses an issue related to
late binding of newly synthesize ivars (when we support it).

about, whether they are builtins or not. Use this to add the
appropriate "format" attribute to NSLog, NSLogv, asprintf, and
vasprintf, and to translate builtin attributes (from Builtins.def)
into actual attributes on the function declaration.

Use the "printf" format attribute on function declarations to
determine whether we should do format string checking, rather than
looking at an ad hoc list of builtins and "known" function names.

Be a bit more careful about when we consider a function a "builtin" in
C++.

ConstraintManager:
- constify getSymVal()

BasicConstraintManager:
- Pull out logic that would be common to ConstraintManagers of a similar nature
  and put them in a parent class called 'SimpleConstraintManager'.

RangeConstraintManager:
- Added a new prototype ConstraintManager to track ranges of variables! This
  ConstraintManager keeps tracks of ranges of concrete integers that a symbolic
  integer may have.

AnalysisConsumer:
- Add driver option to use RangeConstraintManager with GRExprEngine-based
  analyses.

We don't have "zero cost" exceptions for ObjC yet, so there is no codegen

1) implement parser and sema support for reading and verifying attribute(warnunusedresult).
2) rename hasLocalSideEffect to isUnusedResultAWarning, inverting the sense
   of its result.
3) extend isUnusedResultAWarning to directly return the loc and range 
   info that should be reported to the user.  Make it substantially more
   precise in some cases than what was previously reported.
4) teach isUnusedResultAWarning about CallExpr to decls that are 
   pure/const/warnunusedresult, fixing a fixme.
5) change warn_attribute_wrong_decl_type to not pass in english strings, instead,
   pass in integers and use %select.

Don't ignore the const attribute - we even have CG support for that. Do ignore the malloc attribute however.

symbols from an SVal.

- Fixed a bug in EnvironmentManager::RemoveDeadBindings() where it did not mark
  live all the symbols reachable from a live block-level expression.

- Fixed a bug in the retain/release checker where it did not stop tracking
  symbols that 'escaped' via compound literals being assigned to something the
  BasicStoreManager didn't reason about.

we can define builtins such as fprintf, vfprintf, and
__builtin___fprintf_chk. Give a nice error message when we need to
implicitly declare a function like fprintf.
