6dd0246199 Dump clif with --emit llvm-ir in release mode 
Currently it's not possible to dump llvm-ir in release build. With this

always as before.

Fixes #1020

33e73091f8 Don't mark unwind ebbs as cold 
This fixes the code_layout optimization, as it would previously try to
move non-existing ebbs.
