pretty-print a block's terminator.

When building CFGs, for IfStmts ('if'), we no longer add the ParenExpr
that is the subexpression of the IfStmt to the CFG; instead we add its
first descendant subexpression that is not a ParenExpr.

On an unexpected @foo keyword, return failure instead of a 'successful' null AST.  This fixes a segfault
on things like @foo.

codegen of calls to functions without a prototype and varargs functions,

Many refinements to Sema::MergeVarDecl(). This routine still needs some re-work to fully handle tentative decls.

This includes a fix to bz1908.

auto-propagation of state along a branch.

we automatically generate a new successor node along an edge if the checker
did not explicitly do so (i.e., we just propagate the current state).

- Some minor optimizations of the encoding format for ObjCAtSynchronizedStmt.
- Reordered methods so that the deserialization methods for 
  ObjCAtSynchronizedStmt appear in alphabetical order with the corresponding
  methods of the other AST nodes.

Made some internal API cleanups with creating ConcreteInt values, which lead to
some code reduction in implementing "++", "--".

Tighten up ASTContext::typesAreCompatible()...it needs to make sure the qualifiers match. The comment and C99 citation for this routine were correct...the code needed to conform to the comment/spec. This fixes the test added below.

Tightening up this routine forced tweaks to Sema::CheckSubtractionOperands() and Sema::CheckCompareOperands(). For example, they both need to operate on the unqualified pointee...
