Exemplar
target is x86_64
The attached ICEs in expr.c, lowering the second call to Quux to RTL:
<materialize-all-clones> <simdclone> void Frob(const Good&, const Bad&)during
RTL pass: expand
bug.ii: In function 'void Frob(const Good&, const Bad&)':
bug.ii:20:13: internal compiler error: in convert_move, at expr.c:231
Quux (bad.val);
