[Bug middle-end/28915] [4.2 regression] ICE: tree check: expected class 'constant', have 'declaration' (var_decl) in build_vector, at tree.c:973

Hmm, yep I guess it was caused my change, most probably this part of it:

        * tree.c (build_constructor_single): Mark a CONSTRUCTOR as constant,
        if all of its elements/components are constant.
        (build_constructor_from_list): Likewise.

It looks like someplace is changing the contents of this CONSTRUCTOR to a
VAR_DECL "t.0", but not reseting the TREE_CONSTANT flag.  Hence on PPC we
end up with a bogus constant constructor during RTL expansion!?
Scalar replacement perhaps??

Grr.  I'll investigate.  Sorry for the inconvenience.
