Eli Friedman 62f3ef2b53 [CGCall] Annotate references with "align" attribute. 
If we're going to assume references are dereferenceable, we should also
assume they're aligned: otherwise, we can't actually dereference them.

See also D80072.

and 'priority' are not supported in full, only constant expressions can
be used currently in these clauses.
