Fix ICE #101739

Fixes a part of #101739

This cannot cover the following case. It causes `too many args provided` error and obligation does not have references error. I want your advice to solve the following cases as well in this pull request or a follow-up.

```rust
#![crate_type = "lib"]
#![feature(transmutability)]
#![allow(dead_code, incomplete_features, non_camel_case_types)]

mod assert {
    use std::mem::BikeshedIntrinsicFrom;

    pub fn is_transmutable<
        Src,
        Dst,
        Context,
        const ASSUME_ALIGNMENT: bool,
        const ASSUME_LIFETIMES: bool,
        const ASSUME_VALIDITY: bool,
        const ASSUME_VISIBILITY: bool,
    >()
    where
        Dst: BikeshedIntrinsicFrom<
            Src,
            Context,
            ASSUME_ALIGNMENT,
            ASSUME_LIFETIMES,
            ASSUME_VALIDITY,
            ASSUME_VISIBILITY,
        >,
    {}
}

fn via_const() {
    struct Context;
    #[repr(C)] struct Src;
    #[repr(C)] struct Dst;

    const FALSE: bool = false;

    assert::is_transmutable::<Src, Dst, Context, FALSE, FALSE, FALSE, FALSE>();
}
