[PATCH] D66314: [Bugpoint redesign] Output option can now print to STDOUT

[Diego Treviño via Phabricator via llvm-commits]

diegotf created this revision.
diegotf added reviewers: chandlerc, dblaikie, xbolva00.
Herald added a project: LLVM.
Herald added a subscriber: llvm-commits.

This also changes all the outs() statements to errs() so the output and
progress streams don't get mixed.

This has been added because D64176 <https://reviews.llvm.org/D64176> had flaky tests, which I believe were because the reduced file was being catted into `FileCheck`, instead of being pass from STDOUT directly.
