Sean Callanan 9e6ed53ea5 Bugfixes to the expression parser. Fixes include: ...

- If you put a semicolon at the end of an expression,
   this no longer causes the expression parser to
   error out.  This was a two-part fix: first,
   ClangExpressionDeclMap::Materialize now handles
   an empty struct (such as when there is no return
   value); second, ASTResultSynthesizer walks backward
   from the end of the ASTs until it reaches something
   that's not a NullStmt.

 - ClangExpressionVariable now properly byte-swaps when
   printing itself.

 - ClangUtilityFunction now cleans up after itself when
   it's done compiling itself.

 - Utility functions can now use external functions just
   like user expressions.

 - If you end your expression with a statement that does
   not return a value, the expression now runs correctly
   anyway.

Also, added the beginnings of an Objective-C object
validator function, which is neither installed nor used
as yet.
