[PATCH] D38154: [PassManager] Run global opts after the inliner

[Davide Italiano via Phabricator via llvm-commits]

davide added a comment.

This is a proposed solution to PR34652
We could in theory teach the inline some other tricks, but this seems to be harmless and good anyway.
The rust folks ran quite a bit of benchmarks (and saw up to 20% reduction in build time), I ran some internal code and saw up to 5% reductions without any significant increase (within the noise)
cc: @mzolotukhin @Gerolf as they expressed interest in the area.
