Jubilee Young 18a707fc8e Revert "Fix an ICE in the vtable iteration for a trait reference" 
The ICE fix appears to be unsound, causing a miscompilation involving
`dyn Trait` and `async {}` which induces segfaults in safe Rust code.
As the patch only hid an ICE, it does not seem worth the risk.

This reverts commit 8afd63610b, reversing
changes made to 19122c03c7.
