> Log:<br>
> Re-commit r217995 and follow-up patches (r217997, r218011, r218053). These were<br>
> reverted in r218058 because they triggered a rejects-valid bug in MSVC.<br>
><br>
> Original commit message from r217995:<br>
><br>
> Instantiate exception specifications when instantiating function types (other<br>
> than the type of a function declaration). We previously didn't instantiate<br>
> these at all! This also covers the pathological case where the only mention of<br>
> a parameter pack is within the exception specification; this gives us a second<br>
> way (other than alias templates) to reach the horrible state where a type<br>
> contains an unexpanded pack, but its canonical type does not.<br>
