Rollup merge of #34436 - jseyfried:no_block_expr, r=eddyb
...
To allow these braced macro invocation, this PR removes the optional expression from `ast::Block` and instead uses a `StmtKind::Expr` at the end of the statement list.
Currently, braced macro invocations in blocks can expand into statements (and items) except when they are last in a block, in which case they can only expand into expressions.
For example,
```rust
macro_rules! make_stmt {
() => { let x = 0; }
}
fn f() {
make_stmt! {} //< This is OK...
let x = 0; //< ... unless this line is commented out.
}
```
Fixes #34418 .

Rollup merge of #34385 - cgswords:tstream, r=nrc
...
syntax-[breaking-change] cc #31645
(Only breaking because ast::TokenTree is now tokenstream::TokenTree.)
This pull request refactors TokenTrees into their own file as src/libsyntax/tokenstream.rs, moving them out of src/libsyntax/ast.rs, in order to prepare for an accompanying TokenStream implementation (per RFC 1566).

...
`nest_level` is long dead since cac7a2053aba7be214d5e58e13867089638a8f50
(PR #14831 ), so is `check_positional_ok()`. Let's bid them farewell.
