- Two new tests (one for each property), require libclang built from r155858 or later to pass
- New test utility function (get_cursors) that gets all the nodes with a specific spelling.

in-class initializer for one of its fields. Value-initialization of such
a type should use the in-class initializer!

The former was just a bug, the latter is a (reported) standard defect.

Detecting illegal instantiations of abstract types when using a function-style cast.  Fixed PR12658.

[analyzer] Reduce parallel code paths in SimpleSValBuilder::evalBinOpNN, and handle mixed-type operations more generally.

The logical change is that the integers in SymIntExprs may not have the same type as the symbols they are paired with. This was already the case with taint-propagation expressions created by SValBuilder::makeSymExprValNN, but I think those integers may never have been used. SimpleSValBuilder should be able to handle mixed-integer-type SymIntExprs fine now, though, and the constraint managers were already being defensive (though not entirely correct). All existing tests pass.

The logic in evalBinOpNN has been simplified so that conversion is done as late as possible. As a result, most of the switch cases have been reduced to do the minimal amount of work, delegating to another case when they can by substituting ConcreteInts and (as before) reversing the left and right arguments when useful.

Comparisons require special handling in two places (building SymIntExprs and evaluating constant-constant operations) because we don't /know/ the best type for comparing the two values. I've approximated the rules in Sema [C99 6.3.1.8]  but it'd be nice to refactor Sema's actual algorithm into ASTContext.

This is also groundwork for handling mixed-type constraints better than we do now.

for having a uniform logic for adding attributes to a decl. This in turn
is needed to fix the FIXME:

  // FIXME: This needs to happen before we merge declarations. Then,
  // let attribute merging cope with attribute conflicts.
  ProcessDeclAttributes(S, NewFD, D,
                        /*NonInheritable=*/false, /*Inheritable=*/true);

The idea is that mergeAvailabilityAttr will become a method. Once attributes
are processed before merging, it will be called from handleAvailabilityAttr to
handle multiple attributes in one decl:

void f(int) __attribute__((availability(ios,deprecated=3.0),
                           availability(ios,introduced=2.0)));

and from SemaDecl.cpp to handle multiple decls:

void f(int) __attribute__((availability(ios,deprecated=3.0)));
void f(int) __attribute__((availability(ios,introduced=2.0)));

As a bonus, use the new structure to diagnose incompatible availability
attributes added to different decls (see included testcases).

Previously, if an instruction definition was missing the mnemonic,
the next line would just assert(). Issue a real diagnostic instead.

The primitive conservative heuristic seems to give a slight overall
improvement while not regressing stuff. Make it available to wider
testing. If you notice any speed regressions (or significant code
size regressions) let me know!
