Rollup merge of #107695 - Swatinem:futcallx3, r=compiler-errors
Add test for Future inflating arg size to 3x

This adds one more test that should track improvements to generator
layout, like https://github.com/rust-lang/rust/issues/62958 and https://github.com/rust-lang/rust/issues/62575.

In particular, this test highlights suboptimal layout, as the storage
for the argument future is not being reused across its usage as `upvar`,
`local` and `awaitee` (being polled to completion).

This is on top of https://github.com/rust-lang/rust/pull/107692 (as those would conflict with each other)

It is a minimal repro for code mentioned in https://github.com/moka-rs/moka/issues/212#issuecomment-1416914616 (CC `@tatsuya6502)`
