"parameter" types. An intrinsic can now return a multiple return values like
this:

  def add_with_overflow : Intrinsic<[llvm_i32_ty, llvm_i1_ty],
                                    [LLVMMatchType<0>, LLVMMatchType<0>]>;

Correctly connect 'continue' and 'break' statements in Objective-C fast enumeration for blocks to the appropriate basic blocks.

GRExprEngine/CFRefCount/GRSimpleVals: We don't do any special handling (yet) of vector types.  Add explicit checks that when we process integers that they really are scalars.

some more bullet-proofing/enhancements for tryEvaluate.  This shouldn't 
cause any behavior changes except for handling cases where we were 
crashing before and being able to evaluate a few more cases in tryEvaluate.
 
This should settle the minor mess surrounding r59196.

 - Resume running the always inliner pass always now that LLVM has
   been improved and functions with debug info can be inlined.
 - Remove unused header.

the Backend output should be done in binary mode.
 - I'd appreciate it if someone who has a Windows build could verify
   this.

- Don't crash on vector types.
- Handle typedefs.

little rude; I figure it's cleaner to just back this out now so 
it doesn't get forgotten or mixed up with other checkins.

The modification to isICE is simply wrong; I've added a test that the 
change to isICE breaks.

I'm pretty sure the modification to tryEvaluate is also wrong.  
At the very least, there's some serious miscommunication going on here, 
as this is going in exactly the opposite direction of r59105.  My 
understanding is that tryEvaluate is not supposed to care about side 
effects.  That said, a lot of the clients to tryEvaluate are 
expecting it to enforce a no-side-effects policy, so we probably need 
another method that provides that guarantee.

landing pads.
 - Primarily a cleanliness issue instead of a performance issue (this
   eliminates all blocks w/o predecessors on 176.gcc/expr.c), but this
   also allows subsequent code to recognize it is unreachable and
   potentially avoid IRgen.

llvm-svn: 59211

 - Use dotted notation for blocks related to a particular statement
   type.
 - Use .end for landing pads.

No functionality change in NDEBUG mode. :)

 - Indicates that caller is done with the block and it can be dropped
   if it has no predecessors. Useful for callers who need to make
   landing pads but which may not be reached.

more confusing ifelse.

Use dotted names for if blocks (if.then vs ifthen).

Fix bug where the body block of an ObjCForCollectionStmt would not properly get expanded as a series of basic blocks.

 - Evaluation of , operator used bogus assumption that LHS could be
   evaluated as an integral expression even though its type is
   unspecified.

This change is making isICE very permissive of the LHS in non-evaluated 
contexts because it is not clear what predicate we would use to reject 
code here. The standard didn't offer me any guidance; opinions?
