LLVM Assertion: Both operands to ICmp instruction are not of the same type!

Unfortunately, I don't know what in hyper is causing this error.

rustc: /home/rustbuild/src/rust-buildbot/slave/nightly-dist-rustc-linux/build/src/llvm/include/llvm/IR/Instructions.h:997: void llvm::ICmpInst::AssertOK(): Assertion `getOperand(0)->getType() == getOperand(1)->getType() && "Both operands to ICmp instruction are not of the same type!"' failed.

Nevermind, I found it. Using an array pattern in a match against a slice:

fn main() {
    match "foo".as_bytes() {
        b"food" => println!("nom nom"),
        [b'f', ..] => println!("f!"),
        _ => ()
    }
}

Rewrite the pattern matching code in trans.

Visiting for triage: this is still an issue

Still ICE. Updated minimal test case:

#![feature(slice_patterns)]

fn main() {
    match "foo".as_bytes() {
        b"food" => println!("nom nom"),
        [b'f', ..] => println!("f!"),
        _ => ()
    }
}

Does not ICE anymore

Fixed by #40296

rust-lang/rust#23311 no longer ICEs
