More Objective-C fixes

Clang Frontend
#1

Hi,

This fixes message sends to super in a way that both works with real code and passes the test in the test suite. It also fixes a crash when using recent versions of GNU libobjc and compiling modules that do not contain any constant strings but do contain a declaration of the constant string class and possible some other corner cases (thanks to Pete French for providing me with a test case for that one).
