changed).  Use this to implement 'A' constraint on x86.

Always emit a function pointer as a pointer to the function stub (if there is one). This makes it possible to compare function pointer values in lazy compilation mode. This fixes PR3043.

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); }
                     ^

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).
