4.1 cc1plus compiler on sh4-linux fails with the ICE
foo.cc:11: internal compiler error: in gimplify_addr_expr, at gimplify.c:3572
for
struct S
{
double a;
};
void
foo (int z, ...)
{
struct S arg;
__builtin_va_list ap;
arg = __builtin_va_arg (ap, struct S);
}
and 4.2 cc1plus fails with the similar message. sh-elf cc1plus
also fails with -m4.
Binary search shows that it starts to fail just after the patch

* gimplify.c (gimplify_modify_expr_rhs): Disable *& optimization for
now.
PR middle-end/25977
* gimplify.c (gimplify_modify_expr_rhs): It's not always safe to do RVO
on the return slot if it's an NRV.
and the ICE goes away if the first hunk of the patch is reverted.
It seems that the tree made by sh_gimplify_va_arg_expr depends on
that *& optimization which is now disabled.

SH is not a primary platform, so this is P5. However, it's fine (good, in
fact!) to put the patch on the branch if the testing succeeds.
