i'm not sure why test fails on travis.
The CI uses the system LLVM 3.9 for testing, so both conditions are going to be false, meaning these flags won't be applied at all.
You may move these flags into another #if block which does not check LLVM_RUSTLLVM (assume these can apply to the unmodified LLVM), or tag the test case with // no-system-llvm.

…rister Teach rustc about DW_AT_noreturn and a few more DIFlags We achieve two small things with this PR: 1. We provide definitions for a few additional llvm debuginfo flags 1. We _use_ one of these new flags, `FlagNoReturn`, and add it to debuginfo for functions with the never return type (`!`).
