Mike Stump 0509d9635b Ensure we track all the stack depths for all break and continue points 
correctly.  This should lay the ground work to throw the big switch
and start code gening break and continue in the presense of vlas.

Mike Stump 6d8a617474 Ensure that we don't miscodegen if vlas creap into the top of the for. 
This will allow us to generate break and continue even if vlas are
involved without worry that we'll silently generate bad code.

Chris Lattner 5455db4273 make sure that UINTMAX_MAX has an unsigned type. This assumes that 
uintmax_t is unsigned long long, which is not optimal, but is assumed 
elsewhere already.

Daniel Dunbar ee9e4c274b Set load/store alignment when doing ABI coercions. 
- Currently, this is producing poor code, but we prefer correctness
   to performance for now. Eventually we should be able to generally
   avoid having to set the alignment when we control the alignment of
   the alloca.

 - This knocks out 33/1000 failures on my single argument ABI tests,
   down to 22/1000 and 18 of these appear to be gcc bugs. Woot.

Ted Kremenek 0b41d6c43d Use 'Destroy(Context)' instead of 'Context.Deallocate()' (does recursive freeing of memory).

Ted Kremenek 5a201951ca Overhaul of Stmt allocation: 
- 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!

Ted Kremenek 5d7662cfe0 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.

Chris Lattner 01af63beb4 Apparently it is important to define intptr_t and uintptr_t to 
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.
