Patch to get GDC up to 1.028

[shinichiro.h]

Nice work!

I've also tried to make GDC use newer 2.*, but I've not done yet. By
the way I found a bug in your patch. You are so careful that you are
warning this can be a bug though.

http://d.puremagic.com/issues/show_bug.cgi?id=1575

breaks compiler like:

% gdc1 bug1575.d
TupleExp::toElem() tuple(_s_field_0 = _param_0,_s_field_1 = _param_1)
bug1575.d: In function 'foo':
bug1575.d:11: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
EXPER: Uneducated guesswork ensues. Beware.

I think removing TupleExp::toElem from expression.c and adding

elem *
TupleExp::toElem(IRState * irs)
{
    tree result = NULL_TREE;
    for (unsigned i = 0; i < exps->dim; i++) {
	Expression * e = (Expression *) exps->data[i];
	tree elem_e = e->toElem( irs );
	result = irs->maybeCompound(result, elem_e);
    }
    return result;
}

into d-glue.c will work.

Thanks,
