Steffen Lyngbaek 6087c01460 'Fill match arms' should work with existing match arms 
Addresses #3039

This essentially adds missing match arms. The algorithm for this
can get complicated rather quickly so bail in certain conditions
and rely on a PlaceholderPat.

The algorighm works as such:
- Iterate through the Enum Def Variants
- Attempt to see if the variant already exists as a match arm
- If yes, skip the enum variant. If no, include it.
- If it becomes complicated, rather than exhaustively deal with every
  branch, mark it as a "partial match" and simply include the
  placeholder.

  Conditions for "complication":
  - The match arm contains a match guard
  - Any kind of nested destrucuring

Order the resulting merged match branches as such:
1. Provided match arms
2. Missing enum variant branch arms
3. End with Placeholder if required

- Add extra tests
