We were previously just checking whether direct package dependencies had
been modified. This caused issues when compiling without optimisations
as we wouldn't relink the direct dependency if one of its dependenices
changed.

This commit introduces a language extension, `OrPatterns`, as described in proposal 0522.
It extends the syntax by the production
`pat -> (one of pat1, ..., patk)`.
The or-pattern `pat` succeeds iff one of the patterns `pat1`, ..., `patk` succeed, in this order.
Currently, or-patterns cannot bind variables. They are still of great use as they discourage the use of wildcard patterns in favour of writing out all "default" cases explicitly:
```
isIrrefutableHsPat pat = case pat of
...
(one of WildPat{}, VarPat{}, LazyPat{})
= True
(one of PArrPat{}, ConPatIn{}, LitPat{}, NPat{}, NPlusKPat{}, ListPat{})
= False
```
This makes code safer where data types are extended now and then - just like GHC's `Pat` in the example when adding the new `OrPat` constructor. This would be catched by `-fwarn-incomplete-patterns`, but not when a wildcard pattern was used.
