This PR adds basic support for the Multi-Value Proposal. For a tuple type to be considered for multi-value, it must be explicitly marked with readonly first.

Related: #1633 #1425

I accidentally closed #3021 by overwriting history on my fork. Re-opening here. Refer to #3021 for prior discussion

So far, this adds basic compiler/binaryen support for outputting multi-value returns, but does not support things like indexing yet

I'm thinking that the next PR should add support type checking for tuples/multi-values, support indexing, and add an SROA pass to identify array literals vs tuples. After that, full support for tuples probably based off of warpo's implementation

Sorry, something went wrong.

Uh oh!
