[llvm-dev] GSoC19: Debug Info should have no effect on codegen

[Greg Bedwell via llvm-dev]

We've got a meta-bug for these sorts of issues here:
https://bugs.llvm.org/show_bug.cgi?id=37728
You might also be interested in this presentation from a few years back:
https://llvm.org/devmtg/2015-04/slides/Verifying_code_gen_dash_g_final.pdf

I've just set off a test case reduction of a case I ran into on one of our
internal test suites using the check_cfc tool so hopefully I can upload it
as an example bug, attached to the metabug above once that's complete.
