Auto merge of #64525 - nikomatsakis:issue-64512-drop-order-tail-temp, r=davidtwco
adjust desugaring for async fn to correct drop order
Old desugaring, given a user function body `{ $stmts; $expr }`
```
{
let $param_pattern0 = $raw_param0;
...
let $param_patternN = $raw_paramN;
$stmts;
$expr
}
```
New desugaring:
```
{
let $param_pattern0 = $raw_param0;
...
let $param_patternN = $raw_paramN;
drop-temps {
$stmts;
$expr
}
}
```
The drop-temps is an internal bit of HIR that drops temporaries from the resulting expression, but it should be equivalent to `return { $stmts; $expr }`.
Fixes #64512
Fixes #64391
