ICE when using simd Shl/Shr.

[ghost]

The following code:

#![feature(core)]
use std::simd::u32x4;
fn main() {
    let a = u32x4(1, 1, 1, 1);
    println!("{:?}", a >> a);
}

Will cause an ICE:

rustc: /home/rustbuild/src/rust-buildbot/slave/nightly-dist-rustc-linux/build/src/llvm/include/llvm/Support/Casting.h:237: typename llvm::cast_retty<X, Y*>::ret_type llvm::cast(Y*) [with X = llvm::IntegerType; Y = llvm::Type; typename llvm::cast_retty<X, Y*>::ret_type = llvm::IntegerType*]: Assertion `isa<X>(Val) && "cast<Ty>() argument of incompatible type!"' failed.

Tested with:
rustc 1.0.0-nightly (00978a987 2015-04-18) (built 2015-04-19)
