6a2127be28 Cleanup checking for existing impls in impl From assist 
Use the trait solver to check if there's an existing implementation of
From<type_in_enum_variant> for the enum.

1fee60181f Add impl From for enum variant assist 
Basically adds a From impl for tuple enum variants with one field. Added
to cover the fairly common case of implementing your own Error that can
be created from another one, although other use cases exist.

This means we now retain comments when filling in match arms.

Merge #3700 
3700: fill match arms with empty block rather than unit tuple r=matklad a=JoshMcguigan

As requested by @Veetaha in #3689 and #3687, this modifies the fill match arms assist to create match arms as an empty block `{}` rather than a unit tuple `()`.

In one test I left one of the pre-existing match arms as a unit tuple, and added a body to another match arm, to demonstrate that the contents of existing match arms persist.

b5ba9c3e3a Address nits and suggestions. 
Simplify the logic a lot by removing the check for a placeholder pat.
This means the auto-fill no longer returns a compile-able value.

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
