Move setBugReportMsg() out from under a conditional

[probinson]

Summary

Fixes a build break with LLVM_ENABLE_BACKTRACES=OFF.

For some reason my git environment is hosed and I can't commit this directly at the moment.
@leonardchan go ahead and commit this.

I am doing internal integrates and have also read the source. This looks good.

LGTM. Thanks for the fix. I'll go ahead and submit this.

You should have done git commit --amend --author='Paul Robinson <...>' to credit this change properly to Paul.

My bad. I'll keep this in mind for the future.
