where the control reaches the end of a non-void function and also allows the
compiler to generate better code.  When this assertion is false we can easily
add more else cases.

Missing special lookup rule in Sema::ActOnInstanceMessage().

C++ constructors, destructors, and conversion functions now have a
FETokenInfo field that IdentifierResolver can access, so that these
special names are handled just like ordinary identifiers. A few other
Sema routines now use DeclarationNames instead of IdentifierInfo*'s.

To validate this design, this code also implements parsing and
semantic analysis for id-expressions that name conversion functions,
e.g.,

  return operator bool();

The new parser action ActOnConversionFunctionExpr takes the result of
parsing "operator type-id" and turning it into an expression, using
the IdentifierResolver with the DeclarationName of the conversion
function. ActOnDeclarator pushes those conversion function names into
scope so that the IdentifierResolver can find them, of course.

will hopefully never support this.

 - RegionView and RegionViewMap is introduced to assist back-mapping from
   super region to subregions.
 - GDM is used to carry RegionView information.
 - AnonTypedRegion is added to represent a typed region introduced by pointer
   casting. Later AnonTypedRegion can be used in other similar cases, e.g.,
   malloc()'ed region.
 - The specific conversion is delegated to store manager.

Reverted part of r59335: http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20081110/009243.html
In that patch I added a bogus type promotion for unary '!'.

The real bug was more fallout from edges cases with compound assignments and conjured symbolic values.  Now the conjured value has the type of the LHS expression, and we do a promotion to the computation type.  We also now correctly do a conversion from the computation type back to the LHS type.

Implement FIXME in GRExprEngine::VisitUnaryOperator() to handle implicit conversions caused by the '!' operator.  This required adding some logic to GRSimpleVals to reason about nonloc::LocAsInteger SVals.  This code appears to work fine, but it should eventually be cleaned up.
