- Made allocation of Stmt objects using vanilla new/delete a *compiler
  error* by making this new/delete "protected" within class Stmt.
- Now the only way to allocate Stmt objects is by using the new
  operator that takes ASTContext& as an argument.  This ensures that
  all Stmt nodes are allocated from the same (pool) allocator.
- Naturally, these two changes required that *all* creation sites for
  AST nodes use new (ASTContext&).  This is a large patch, but the
  majority of the changes are just this mechanical adjustment.
- The above changes also mean that AST nodes can no longer be
  deallocated using 'delete'.  Instead, one most do
  StmtObject->Destroy(ASTContext&) or do
  ASTContextObject.Deallocate(StmtObject) (the latter not running the
  'Destroy' method).

Along the way I also...
- Made CompoundStmt allocate its array of Stmt* using the allocator in
  ASTContext (previously it used std::vector).  There are a whole
  bunch of other Stmt classes that need to be similarly changed to
  ensure that all memory allocated for ASTs comes from the allocator
  in ASTContext.
- Added a new smart pointer ExprOwningPtr to Sema.h.  This replaces
  the uses of llvm::OwningPtr within Sema, as llvm::OwningPtr used
  'delete' to free memory instead of a Stmt's 'Destroy' method.

Big thanks to Doug Gregor for helping with the acrobatics of making
'new/delete' private and the new smart pointer ExprOwningPtr!

GRExprEngine: When processing compound assignments, do a switch table lookup to get the non-compound opcode from the compound opcode instead of relying on the order of BinaryOperator::opcode values.  This unbreaks the misc-ps.c test.

long instead of int.  This is because system heaers like to redefine
typedefs and that is an error if they don't exactly match.  Use long
for intptr_t on all systems where long is the right size.

don't typecast CHAR_MIN to char, this makes it not a PP constant
and gives it the wrong unpromoted type.  Thanks to Sebastian for

redeclarations. For example, checks that a class template
redeclaration has the same template parameters as previous
declarations.

Detangled class-template checking from ActOnTag, whose logic was
getting rather convoluted because it tried to handle C, C++, and C++
template semantics in one shot.

Made some inroads toward eliminating extraneous "declaration does not
declare anything" errors by adding an "error" type specifier.

ASTContext. This required changing all clients to pass in the ASTContext& to the
constructor of StringLiteral. I also changed all allocations of StringLiteral to
use new(ASTContext&).

Along the way, I updated a bunch of new()'s in StmtSerialization.cpp to use the
allocator from ASTContext& (not complete).
