  Log Message:
  -----------
  [InstrProf] Don't profile merge by default in lightweight mode

Profile merging is not supported when using debug info profile
correlation because the data section won't be in the binary at runtime.
Change the default profile name in this mode to `default_%p.proflite` so
we don't use profile merging.
