Fix <rdar://problem/6191148> [sema] Objective-C method lookup (at global scope) fails to handle overloaded selectors properly.

Long standing bug in Sema::ActOnInstanceMessage(). We now warn when messaging an "id" with multiple method signatures in scope. The diags are a little verbose, however they can be streamlined if necessary.

 - Provides a basic primitive to jump to an arbitrary basic block,
   through the finally code.

 - Only used for return statements and rethrow currently. Still need
   to handle break, continue and goto.

 - Code still needs to be shuffled around to live elsewhere.

NumericLiteral parser is not careful about overrun because
it should never be possible.  It implicitly expects that its
input matched the regex for pp-constant.  Because of this, it
knows it can't be pointing to a prefix of something that
looks like a number.  This is all fine, except that __LINE__
does not prevent implicit concatenation from happening.  Fix
__LINE__ to not do this.

 - There is no need to branch on the rethrow variable to determine if
   we need to call objc_exception_try_exit. We know whether an
   exception was thrown, so just branch to a different target if we
   want to skip the try_exit. 

   This is a slight semantic departure from gcc, but only for throwing
   nil, which is undefined (and for which gcc emits broken code).

 - Also fixes a bug in current code which was calling try_exit too
   many times when an exception was uncaught (but there were some
   handlers).

Fix bug introduced in prev. commit, the type of the @catch parameter
was uninitialized.
