In --only-merge mode, the script terminates after the profile merging step. This makes the script less stateful: it's more natural to split the merge out into a separate step instead of relying on the first invocation of the script to do it. This should not break any existing users of the script. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@285247 91177308-0d34-0410-b5e6-96231b3b80d8
