The regression reported in PR c++/8913 showed up starting with this
patch, which might merely uncover an existing problem:

Here's a small test case that causes the ICE, which occurs in the
mainline:
---------------
template <class T> struct Ref {
Ref(int *);
~Ref();
};
struct User{
User (Ref<int> obj) {};
};
void test() {
User a (0);
}
---------------
Output from the compiler:
8913.C: In function `void test()':
8913.C:7: internal compiler error: in simplify_gen_subreg, at simplify-rtx.c:
2673

This information will also be added to the PR.
I'm working on a script to automate the search for regressions down to
the hour; the rest happens manually.
