Merge #846

846: WIP: Enable parsing of attributes inside a match block r=matklad a=vipentti

We allow invalid inner attributes to be parsed, e.g. inner attributes that are
not directly after the opening brace of the match block.

Instead we run validation on `MatchArmList` to allow better reporting of errors.

This fixes #845 and works towards #759
