Set of repro files

While using IRPGO and during an LTO build, IRMover is throwing an error when
trying to merge the ProfileSummary module metadata.
"linking module flags 'ProfileSummary': IDs have conflicting values"
Is throwing an error the correct behavior to have when merging ProfileSummary
metadata?

The attachment contains a trivial case I used to reproduce.
