fixes PR2476; patch by Richard Osborne.  The same
problem exists for a bunch of other operators, but
I'm ignoring this because they will be automagically
fixed when the new LegalizeTypes infrastructure lands,
since it already solves this problem centrally.

"this patch adds code generation hooks for Objective-C constant strings.  It also modifies Sema so that Objective-C constant strings are treated as untyped objects if the interface for the constant string class can not be found.  This is consistent with Apple GCC.  I thought it was consistent with GNU GCC, since this was causing failures when trying to compile GNUstep with (GNU) GCC, but it appears that this is not the case when attempting to produce a simple test case to demonstrate it.  Possibly there is a way of making the error go away, but I haven't found out what it is yet."

"This moves built-in Objective-C types up the scope chains to where they can be replaced by versions included from the runtime library's headers."

This makes it ok to use @"foo" without a declaration for NSConstantString.

since handling this correctly is quite complex, and on some platforms  
requires additional -D options and on some implies linking against a  
different libc, but this works better than just ignoring the option.

The other change passes the -x option across to clang, which allows  
compiling .c files as Objective-C and so on.  For some reason a lot of  
configure scripts seem to be under the misguided impression that this  
is a sensible thing to do."
