IGI-111 30f869a3a8 Implement OR match pattern (#4348) ... ## Description Allow users to specify match patters such as: ```sway let x = 1; match x { 0 | 1 => true, _ => false } ``` We also check that all patterns in a disjunction declare the same set of variables (not doing so is an error). Fix https://github.com/FuelLabs/sway/issues/769 This requires a change in the pattern matching analysis to remove the assumption that a specialized matrix of a vector pattern is always a vector, which is now no longer true because or patterns can generate multiple branches and therefore multiple rows. ## Checklist - [x] I have linked to any relevant issues. - [x] I have commented my code, particularly in hard-to-understand areas. - [x] I have updated the documentation where relevant (API docs, the reference, and the Sway book). - [x] I have added tests that prove my fix is effective or that my feature works. - [x] I have added (or requested a maintainer to add) the necessary `Breaking*` or `New Feature` labels where relevant. - [x] I have done my best to ensure that my PR adheres to [the Fuel Labs Code Review Standards](https://github.com/FuelLabs/rfcs/blob/master/text/code-standards/external-contributors.md). - [x] I have requested a review from the relevant team or maintainers.
