Directly calling "x86-interrupt" fn should be invalid

[workingjubilee]

I tried this code:

#![feature(abi_x86_interrupt)]
extern "x86-interrupt" fn lol() {
    
}

fn main() {
    lol();
}

I expected to see rustc reject the erroneous code somewhere before final LLVM lowering, because the notion of "calling" an interrupt is nonsensical, no matter what its signature is.

Instead, this happened:

rustc-LLVM ERROR: X86 interrupts may not be called directly
