Allow as-patterns in unidirectional patttern synonyms
This patch implements GHC Proposal #94, described here
https://github.com/ghc-proposals/ghc-proposals/pull/94
The effect is simply to lift a totally-undocumented restriction to
unidirecional pattern synonyms, namely that they can't have as-patterns
or n+k patterns.
The fix is easy: just remove the checks.
I also took the opportunity to improve the manual entry for
the semantics of pattern matching for pattern synonyms.
