Fix an obscure rewriter bug when rewriting implementations that don't have a corresponding interface (found while doing random testing on another bug).

1. In the top level of ParseStatementOrDeclaration, don't eat a } if we
   just parsed a statement if it list there.  Also, don't even bother
   emitting an error about a missing semicolon if the statement had a 
   bug (an rbrace is fine).
2. In do/while parsing, don't require a 'while' to be present if the do
   body didn't parse.

This allows us to generate a clean diagnostic for this code:

t.c:1:22: error: expected expression
void foo (void) { do . while (0); }
                     ^

Thanks to Neil for pointing this out.

Using llvm::OwningPtr<> for CurLexer and CurTokenLexer.  This makes both the ownership semantics of these objects explicit within the Preprocessor and also tightens up the code (explicit deletes not needed).

Use PushIncludeMacroStack/PopMacroStack instead of manually pushing/popping from IncludeMacroStack.  This is both cleaner and makes the include stack transparently extensible.

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.

   this.

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

 - Logic such as this quite possibly should be optional builder
   behavior.

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. :)

llvm-svn: 59210

llvm-svn: 59209

 - 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.

No functionality change.
