Slightly smaller:

struct S([bool; f as usize]);
fn f() -> T {}

Assigning P-medium as discussed as part of the Prioritization Working Group procedure and removing I-prioritize.

Still ICEs, but the error message has changed several times. Here's the current ICE for the "slightly smaller" testcase:

error: internal compiler error: compiler/rustc_middle/src/ty/cast.rs:99:13: Attempting to cast non-castable types fn() -> [type error] {f} and usize
