Next round of x87 long double stuff.
Getting close now, basically works.

This method is used to determine if an expression contains implicit
control-flow, and thus appears in a distinct statement slot in the CFG.

For example:

  (1) x = ... ? ... ? ...

  logically becomes:

  (1) ... ? ... : ...  (a unique statement slot for the ternary ?)
  (2) x = [E1]         (where E1 is actually the ConditionalOperator*)

A client of the CFG, when walking the statement at (2), will encounter
E1.  In this case, hasImplicitControlFlow(E1) == true, and the client
will know that the expression E1 is explicitly placed into its own statement
slot to capture the implicit control-flow it has.

where not reversing the order of their subexpression blocks.

Added feature where CallExprs are placed in their own statement slot in
a CFGBlock.  Thus we have a designated "return site" within a CFGBlock when
reasoning about function calls.

- Add an ObjcIvarDecl AST node (a subclass of FieldDecl).
- Instantiate the node in Sema::ParseField(), based on the type of the TagDecl.
- Add Sema::ObjcAddInstanceVariable(), responsible for adorning/adding the ObjcIvarDecl.

First bits of x86 long double constants handling 
(untested, probably does not work).

if the assigned value is a constant expression, e.g.:

int x = 0;

We then check to see if "x" is ever reassigned later.  If so, we don't
emit a warning.  This is because programmers frequently use defensive
programming to make sure a variable has a defined value.

though they should.  On the other hand, everyone seems
to pass such vectors with elements ordered by increasing
index, so rather than sorting the elements simply assert
that the elements are ordered in this way.
