  Changed paths:
    M llvm/lib/IR/DebugInfoMetadata.cpp
    M llvm/unittests/IR/MetadataTest.cpp

  Log Message:
  -----------
  [Metadata] Return the valid DebugLoc if one of them is null with -pick-merged-source-locations. (#138148)

Previously when getMergedLocation was passed nullptr as one of the
parameters we returned nullptr. Change that behaviour to instead return
a valid DebugLoc. This is beneficial for binaries from which SamplePGO
profiles are obtained.
