clamp on std integer types should probably have a better error message and ideally track caller

when running this code

fn main() {
    println!("{}", 0u8.clamp(7,3))
}

i get the following output

thread 'main' panicked at /playground/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library/core/src/cmp.rs:1078:9:
assertion failed: min <= max

this is very unhelpful in any non-trivial codebase that uses this method.
this is a pretty niche error but it can happen.

something like

thread 'main' panicked at src/main.rs:3:20:
invalid clamp range : there are no numbers smaller than 7 and greater than 3

would be ideal, but any improvement would be good.

Start in library/core/src/cmp.rs around the reported assertion at line 1078 and inspect how integer clamp validates its bounds. Determine the expected panic wording and whether the failure can report the caller location, then verify the behavior with the provided 0u8.clamp(7, 3) example and the relevant existing standard-library tests.
