  Revert "[Profile] Allow online merging with debug info correlation."

This reverts commit cf2cf195d5fb0a07c122c5c274bd6deb0790e015.
This breaks merging profiles when nothing is instrumented, see comments in https://reviews.llvm.org/D157632.

This also reverts follow-up commit bfc965c54fdbfe33a0785b45903b53fc11165f13.
