Fix the previous (short lived:-) FIXME.

I didn't realize that GCC considers this a hard error (I thought it was built-in).

Since it's not, we should simply emit an error.

[dylan:~/llvm/tools/clang] admin% cc -c trivial.m
trivial.m:6: error: cannot find interface declaration for 'NSConstantString'

visits its decls, rather than just creating an "end()" iterator.

Fixed child_end() for statements and expressions to use
child_iterator() to create the end() iterator, rather than just
returning NULL.

Fixed bug in StmtIterator where we did not correctly detect if we had
marched off the end of the ScopedDecls.

Add a FIXME to an assert.
Change a dyn_cast_or_null back to cast (which is more efficient).

Tweak a recent fix to UsualArithmeticConversions (made by Chris - r43113). The benefit of this tweak is it guarantees the entire routine operates on unqualified types (which I believe is a bit clearer).

and StmtIteratorImpl (templated), which StmtIterator and
ConstStmtIterator now succintly subclass.

Implemented iteration over the initializers in DeclStmts.  This is not
thoroughly tested, so there may be bugs.

Fix a bug in Sema::CheckConditionalOperands(). When mixing pointers and null pointer constants, we need to promote the null pointer constant (which is an integer) to the pointer type. Test case is self explanatory.

This surfaced yesterday, when compiling test/Sema/cocoa.m on Leopard. Since this has nothing to do with ObjC, it's kind of bizarre this hasn't shown up before. I imagine Cocoa.h on Leopard may have changed recently? 

Thanks to Ted for localizing the bug and giving me a useful AST dump...

when comparing "float" and "const float".  This "fixes" the
issue, but may not be the right fix.  Steve, please review.

Testcase here: test/Sema/usual-float.c

Fix the following bug...

unsigned char asso_values[] = { 34 };
int legal2() { 
  return asso_values[0]; 
}

The code that creates the new constant array type was operating on the original type.

As a result, the constant type being generated was "unsigned char [1][]" (which is wrong).

The fix is to operate on the element type - in this case, the correct type is "unsigned char [1]"

I added this case to array-init.c, which clearly didn't catch this bogosity...

that will (soon) allow iteration over the initializers in
declarations.  This new iterator mechanism is implemented by the
classes StmtIterator and ConstStmtIterator.

Patched a few files to use "operator++" instead of "operator+" on
child_iterators.

Friendship added in VarDecl to StmtIterator to allow returning a
reference to the initializer within the VarDecl.  We may not wish this
as a permanent solution.

we currently turn:

    c = @encode(char *)[2] + 4;

into:

    c = "foo"[2] + 4;

Right now the foo string is hard coded, but you can imagine a world
where it wouldn't be :)
