Merge #11598 
11598: feat: Parse destructuring assignment r=Veykril a=ChayimFriedman2

Part of #11532.

Lowering is not as easy and may not even be feasible right now as it requires generating identifiers: `(a, b) = (b, a)` is desugared into
```rust
{
    let (<gensym_a>, <gensym_b>) = (b, a);
    a = <gensym_a>;
    b = <gensym_b>;
}
```

rustc uses hygiene to implement that, but we don't support hygiene yet.

However, I think parsing was the main problem as lowering will just affect type inference, and while `{unknown}` is not nice it's much better than a syntax error.

I'm still looking for the best way to do lowering, though.

Fixes #11454.

d9f0731bd2 Parse destructuring assignment 
The only patterns we should parse are `..` in structs and `_`: the rest are either not supported or already valid expressions.

2bf81922f7 internal: more reasonable grammar for blocks 
Consider these expples

        { 92 }
  async { 92 }
    'a: { 92 }
   #[a] { 92 }

Previously the tree for them were

  BLOCK_EXPR
    { ... }

  EFFECT_EXPR
    async
    BLOCK_EXPR
      { ... }

  EFFECT_EXPR
    'a:
    BLOCK_EXPR
      { ... }

  BLOCK_EXPR
    #[a]
    { ... }

As you see, it gets progressively worse :) The last two items are
especially odd. The last one even violates the balanced curleys
invariant we have (#10357) The new approach is to say that the stuff in
`{}` is stmt_list, and the block is stmt_list + optional modifiers

  BLOCK_EXPR
    STMT_LIST
      { ... }

  BLOCK_EXPR
    async
    STMT_LIST
      { ... }

  BLOCK_EXPR
    'a:
    STMT_LIST
      { ... }

  BLOCK_EXPR
    #[a]
    STMT_LIST
      { ... }

58d2ece88a internal: overhaul code generation 
* Keep codegen adjacent to the relevant crates.
* Remove codgen deps from xtask, speeding-up from-source installation.

This regresses the release process a bit, as it now needs to run the
tests (and, by extension, compile the code).
