$ rustc test.rs --emit=asm,llvm-ir -O --crate-type=rlib -o testold

emits single file testold with LLVM-IR in it. Previously it used to emit testold.s and testold.ll.

This is a stable→stable regression. 1.14.0 works as expected, 1.16.0 does not. Did not test 1.15.0.

    @arielb1 did you perhaps mean to link a different PR?

    I took the liberty of P-high, but somebody needs to be assigned cc @rust-lang/compiler @rust-lang/tools
