Properly handle alpha to coverage state in non-cloning codepath
Also improve the alpha to coverage handlign in the helpers by using
a single function rather than two.
This removes GL errors about bad glFace enum values (caused by bad
handlign of alpha to coverage in switch statement, which led to a
FrontFace state being created with bad data).
