[PATCH] D64610: [clang] allow -fthinlto-index= without -x ir

[Bob Haarman via Phabricator via cfe-commits]

inglorion added a comment.

This was suggested on D64458 <https://reviews.llvm.org/D64458>.

If we take this change, D64458 <https://reviews.llvm.org/D64458> can be simplified to just accepting -fthinlto-index= as a CoreOption without needing any further changes to Driver.cpp.

I also changed the error message in this change to reflect the fact that we no longer require -x ir; we just require the input to be a bitcode file.
